While many process steps, hereinafter described, are common to the preparation of both the pyrindine and quinoline derivatives of this invention, for convenience, process steps limited to the preparation of quinoline derivatives will be discussed separately following the discussion relating to the preparation of the pyridine derivatives.

In these reactions, the alcohol can function both as reactant and solvent. As such, a secondary solvent is not required. However, when an expensive alcohol is employed in the reaction, a less expensive secondary solvent, such as dioxane, tetrahydrofuran or other non-protic solvent, may be added to the reaction mixture. The amount of non-protic solvent added to the reaction mixture may be widely varied.

The reaction mixture is heated to a temperature between 100"C and 1500C, and water is removed from the reaction mixture during the reaction using any convenient means, e.g., a Dean-Stark water separator.At least one equivalent of alcohol, represented by the formula (V) R3OH, wherein R3 represents a member other than hydrogen or a salt-forming cation, and R1, R2, X, Y and Z are as hereinabove described, is then added to the reaction mixture and the thus prepared mixture heated to reflux at a temperature between 1 000C and 150"C to yield the formula (1 b) 2-(2-imidazolin-2-yl)pyrindine ester. The overall reaction can be graphically illustrated as follows:

The reaction is preferably conducted in the presence of an inert organic solvent, such as toluene or benzene. Good yields of the hydrochloride salt of the desired formula (Ib) ester the attained. The hydrochloride salt is then readily converted to the formula (lb) ester by dissolution of the acid addition salt in water and neutralization of the thus-prepared solution with base, such as sodium or potassium carbonate.The overall reactions can be illustrated as follows:
wherein A is COOR3 and R2 is a substituent other than hydrogen or a salt-forming cation, and R1, R2, X, Y and Z are as hereinabove described.

The reaction mixture is stirred at room temperature from about four to eight hours and then the POCK, removed in vacua. The remaining residue is dispersed in an organic solvent such as toluene. The solvent is removed and the residue dispersed in water and heated to between 80"C and 100"C. After cooling, the pH of the aqueous mixture is adjusted to 5-6 with sodium bicarbonate, and the product extracted into methylene chloride to give the desired formula (Ib) 2-(2-imidazolin-2-yl)pyrindine ester.The reaction can be graphically illustrated as follows:
where A is COOR3 and R3 is a substituent other than hydrogen or a salt-forming cation, and R1, R2, X, Y and Z are as described above.
The formula (lb) 2-(2-imidazolin-2-yl)pyridine ester in which A is COOR3 and R2 is alkyl C,-C,2, alkenyl C3-C,2, alkynyl C3-C10, cycloalkyl C3-C6 or the substituted derivatives of these groups and
X, Y, Z, Rl and R2 are as described above, may be converted to the corresponding amide where
A is CONH2 by reaction with ammonia under superatmospheric pressure at a temperature between about 25"C and 125"C. This reaction can be conducted in a protic solvent such as a lower alkanol or an aprotic solvent such as tetrahydrofuran, dioxane or the like. Likewise, using similar conditions but substituting hydroxylamine for ammonia in the above reaction yields the hydroxamic acid.These reactions may be graphically illustrated as follows:
Treatment of the thus prepared primary amide described above with titanium tetrachloride and triethylamine, preferably in the presence of an inert aprotic solvent, such as tetrahydrofuran yields the corresponding nitrile. The reaction is generally conducted under a blanket of inert gas, such as nitrogen, at a temperature between about O"C and 10 C. The reaction may be illustrated as follows:
where X, Y, Z, R, and R2 are as described above.
Preparation of the formula (VIII) N-substituted imidazolinone derivatives, wherein B is COR4 or
SO2R5; and A is CH2, CN or COOR3; and W is 0; and Rl, R2, R3, X, Y and Z are as described above, excepting that R3 cannot be H or a salt-forming cation and Y and Z cannot be alkylamino, hydroxy or hydroxyloweralkyl; can be achieved by reaction of the appropriately substituted formula (I) 2-(2-imidazolin-2-yl)pyrindine with an excess of acyl halide, acyl anhydride, or sulfonyl halide, alone or in a solvent such as pyridine or toluene at an elevated temperature between about 50"C and 125"C. The reaction can be graphically illustrated as follows:
where A is CH2, CN or COOR3; R1, R2, R3, R4,R5, X, Y and Z are as described above excepting that Y and/or Z cannot be alkylamino, hydroxyl, hydroxyloweralkyl.
Reaction of either the formula (I) 2-(2-imidazolin-2-yl)pyrindine or the formula (VIII) N-substituted imidazolinone derivatives, described and illustrated immediately above, wherein A is CH2, CN or
COOR3 provided that R2 is as described above, excepting that it cannot be an unsaturated alkyl group, B is R4CO or R5SO2 and Y or Z cannot be alkylamino, alkylthio or dialkylamino; with an excess of m-chloroperbenzoic acid in the presence of an inert solvent such as methylene chloride, at refluxing temperature, yields the N-oxide corresponding to the pyrindine derivative utilized as starting material.The reaction may be illustrated as follows:
M-CHLOROPERBENZOIC ACID where A is CH2, CN or COOR3 is as described above excepting that R2 cannot be an unsaturated alkyl group; B is COR4 or SO2R5, Rl, R2, R4, R5, X, Y and Z are as described above excepting that Y and Z cannot be alkylamino, alkylthio or dialkylamino.
Hydrolysis of the thus prepared N-oxide using a strong base such as sodium hydroxide in a lower alcohol yields the corresponding N-oxide in which B is H.
Advantageously, formula (I) esters in which B is hydrogen; W is oxygen and A is COOR3 wherein R2 is a saturated C,-C,2 alkyl, C2-C6 cycloalkyl or benzyl substituent, and R1, R2, X, Y and Z are as defined above; can be prepared by reaction of the corresponding acid, i.e., where
A is COOH, with an appropriate alcohol in the presence of a catalytic amount of a strong mineral acid such as hydrochloric acid, sulfuric acid or the like; at a temperature between about 50 C and 100 C. The reaction may be illustrated as follows:
wherein R2, is C,-C,2 alkyl, C2-C6 cycloalkyl or benzyl; and R1, R2, X, Y and Z are as defined above.
The formula (I) acid as shown immediately above where A is COOH; B is hydrogen; W is oxygen and R1, R2, X, Y and Z are as defined above, is also readily converted to the corresponding methyl ester by reaction with diazomethane at a temperature between about 0 C and 25 C. The thus prepared methyl ester may then be reacted with an alkali metal alkoxide such as a sodium or potassium alkoxide, for convenience shown as R3ONa, and an appropriate alcohol represented by the structure R3OH, wherein R2 is C,-CI2 alkyl optionally substituted with one
C1-C3 alkoxy, C3-C6 cycloalkyl, benzyloxy, furyl, phenyl, halophenyl, loweralkylphenyl, loweralkoxyphenyl, nitrophenyl or cyano; C3-C12 alkenyl optionally substituted with one or two C1-C3 alkoxy, phenyl or halogen groups;C3-C6 cycloalkyl optionally substituted with one or two C1-C3 alkyl groups or with C3-C10 alkynyl optionally substituted with one or two C1-C3 alkyl groups.
The above reactions may be illustrated as follows:
wherein R1, R2, R2, X, Y and Z are as defined above.
Conversion of the above-identified formula (I) esters to their corresponding acid addition salts is readily achieved by treatment of said esters with strong acids, particularly strong mineral acids such as hydrochloric acid, sulfuric acid or hydrobromic acid.
Where the hydrohalide acid addition salts are desired, the formula (I) ester, wherein A is
COOR3 and R3 is other than hydrogen or a salt-forming cation, and R1, R2, X, Y and Z are as described above, is dissolved in an organic solvent such as methylene chloride, chloroform, ether or the like. Addition of at least one equivalent of acid to the thus-prepared solution then yields the desired acid addition salt. The reaction may be illustrated as follows:
When the sulfuric acid salt of the ester is desired, the formula (I) ester is generally dissolved in a lower aliphatic alcohol such as methanol, ethanol, isopropanol or the like or mixtures of the above with water. Treatment of the mixture with at least one equivalent of sulfuric acid yields the sulfuric acid addition salt of the formula (I) ester.
In a further embodiment of the invention, the formula (i) compounds, wherein A is COOT, and Ra is hydrogen and R1, R2, X, Y and Z, are as defined above, except that X, Y and Z cannot be NO2 or halogen, can be prepared by hydrogenolysis of the benzyl ester of the imidazolinyl pyridine shown in formula (XV), wherein R1, R2, X, Y and Z, are as above-defined employing a palladium or platinum catalyst. In this reaction, the formula (XV) benzyl ester is dissolved or dispersed in an organic solvent, such as lower alcohol, an ether such as dioxane, tetrahydrofuran or the like, toluene or xylene.The catalyst, preferably palladium on a carbon carrier, is added to the mixture and the mixture heated to between 20 C and 50 C. The heated mixture is then treated with hydrogen gas to yield the desired acid. The reaction may be graphically illustrated as follows:
Alternatively, the formula (I) acids where A is COOH may be prepared by treatment of an aqueous solution of the formula (I) ester with a strong base. In practice the formula (I) ester is generally treated with one equivalent of base in aqueous solution, and the mixture heated to between 20"C and 50 C. The mixture is then cooled and adjusted to pH 6.5 to 7.5 and preferably pH 7, with a strong mineral acid. Such treatment yields the desired acid.The reaction can be illustrated as follows:
where Ra is other than hydrogen or a salt-forming cation, and R1, R2, X, Y and Z are as described with reference to formula (I).
The formula (I) acids wherein A is COOH; B is hydrogen; W is oxygen and X, Y, Z, R, and R2 are as described, can be prepared by reaction of the appropriately substituted formula (XVIII) imidazolinone with alkyl lithium, preferably in the presence of an inert solvent such as tetrahydrofuran under a blanket of nitrogen at a temperature between about -70"C and -80"C. The thusformed mixture is then treated with hexamethylphosphoramide and carbon dioxide preferably in an inert solvent such as tetrahydrofuran, to yield the desired product.When it is desirable to obtain the formula (I) pyridine derivatives in which A is CH3 and X, Y, Z, R, and R2 are as stated above, the formula (XVIII) imidazolinone is treated in the same manner as described for the preparation of the acid, excepting that methyl iodide is substituted for the carbon dioxide. If dimethylformamide is substituted for the methyl iodide, the corresponding formyl derivatives are obtained. These reactions may be illustrated as follows:
Advantageously, the formula (I) imidazolinones can be prepared by a rather unique procedure involving heating, from about 1 to 20 equivalents and preferably at least 1.5 equivalents of a 5substituted formula (LXX) 2-picoline with at least 1 equivalent of an appropriate formula (XIII) aminocarboxamide in the presence of at least 3 equivalents of sulfur.In this reaction, at least a 3 to 1 ratio of sulfur to aminocarboxamide is essential for good product yields. Also, at least 1 and preferably 1.5 equivalents of the picoline is required for good product yields. However, with regard to the picoline, it is found that said compound, while being a reactant, may also be used as a solvent for the reaction mixture and used in large excess. The reaction mixture is boiled, and the vapors therefrom passed through a column packed with molecular sieves to remove any water formed during reaction. The dried condensate is then returned to the reaction vessel, and heating of the mixture is continued for several hours. Thereafter, the mixture is cooled, dissolved in an organic solvent such as ethyl acetate, diethyl ether or the like and filtered. The filtrate is extracted with aqueous mineral acid such as sulfuric acid or hydrochloric acid, and the aqueous phase treated with aqueous base to liberate the formula (I) imidazolinone. If the product precipitates as a solid, it is recovered by filtration; if as an oil, it is extracted into a solvent such as dichloromethane, ether, and the like, and the product purified by conventional methods.The reaction may be graphically illustrated as follows:
wherein Z is hydrogen; Y is hydrogen, C,-C6 alkyl, C,-C6 alkoxy, phenyl or substituted phenyl; A is hydrogen, CH3 or COOT, where Ra is C,-CI2 alkyl and R, and R2 are Cl-C4 alkyl; and when taken together, they may represent C2-C6 cycloalkyl optionally substituted with methyl and when Rl and R2 are not the same, the optical isomers thereof; and when taken together, Y and Z may form a ring in which YZ is -CH=CH-CH=CH- and A, R1, R2 and R2 are as described above.
Said process is thus highly effective for preparing variously substituted formula (XVIII) imidazolinones from 2-picolines and substituted quinaldines.
Preparation of the 5-alkoxy-2-picoline employed in the above reaction for the preparation of 2 (5-alkoxy-2-pyridyl)-5 ,5-di(lower)alkyl-2-imidazolin-4-one compounds is achieved by reacting 5hydroxy-2-methyl-pyridine with an equivalent amount of a C,-C4 alkyl iodide in the presence of sodium hydride and a solvent such as dry dimethylformamide at a temperature of from 0 to 5"C under a blanket of inert gas such as nitrogen.
Advantageously, the formula (I) acids may be converted to the formula (VII) 5-H-imida zo[ 1,2': 1 ,2]-pyrrolo[3 ,4-b]pyridine-3 (2H) 5-diones by reaction with dicyclohexylcarbodiimide (DCC). The reaction is preferably conducted using approximately an equimolar amount of the carbodiimide in the presence of a chlorinated hydrocarbon solvent at a temperature between about 20"C to 32 C.The reaction may be graphically illustrated as follows:
The formula (VII) 5H-imidazo[1',2':1,2]pyrrolo[3,4-b]pyridine-3(2H),5-diones are isomers of the formula (Ill) imidazopyrrolopyridinediones referred to above, and are especially useful in the preparation of a variety of the formula (I) 2-(2-imidazolin-2-yl)-pyridine derivatives of the present invention, as will become apparent from the following discussion.
In practice, it is found that the formula (VII) 3(2H),5-diones can be reacted with at least one equivalent of an appropriate formula (V) R2OH alcohol in the presence of triethylamine as catalyst to yield the formula (I) pyridine ester corresponding to the alcohol used. The reaction is preferably conducted at a temperature between about 20 C and 50"C in the presence of an inert aprotic solvent, such as tetrahydrofuran, dioxane or the like. The reaction may be illustrated as follows:
wherein R2 represents a substituent as described above, excepting that hydrogen and saltforming cations are excluded, and R1, R2, X, Y and Z, are as described above.

Formula (I) compounds, wherein A is COOR3 and Ra represents a salt-forming cation such as an alkali metal, alkaline earth metal, ammonium or aliphatic ammonium and R1, R2, X, Y and Z are as described above, can be prepared by dissolving the formula (I) 2-(2-imidazolin-2-yl)pyrindine acid in an appropriate solvent and, thereafter, treating the solution of the acid with one equivalent of salt-forming cation. For compounds in which the salt-forming cation is an inorganic salt such as sodium, potassium, calcium, barium or the like, the formula (I) acid may be dissolved or dispersed in water or a lower alcohol or mixtures thereof. One equivalent of the salt-forming cation generally in the form of the hydroxide, carbonate, bicarbonate or the like, but preferably as the hydroxide, is admixed with the solution of the formula (I) acid.After several minutes, the formula (I) compound, wherein Ra is the inorganic salt-forming cation, generally precipitates and can be recovered from the mixture by either filtration or through azeotropic distillation with an organic solvent such as dioxane.
To prepare the formula (I) compound in which A is COOR3 and Ra is ammonium or organic ammonium, the formula (I) acid is dissolved or dispersed in an organic solvent such as dioxane, tetrahydrofuran or the like, and the mixture treated with one equivalent of ammonia or the amine or the tetralkylammonium hydroxide.Among the amines which may be used in the above-said reaction are: methylamine, ethylamine, n-propylamine, iso-propylamine, n-butylamine, isobutylamine, sec-butylamine, n-amylamine, hexylamine, heptylamine, octylamine, nonylamine, decylamine, undecylamine, dodecylamine, tridecylamine, tetradecylamine, pentadecylamine, hexadecylamine, heptadecylamine, octadecylamine, methylethylamine, methylisopropylamine, methylhexylamine, methylnonylamine, methylpentadecylamine, methyloctadecylamine, ethylbutylamine, ethylheptylamine, ethyloctylamine, hexylheptylamine, hexyloctylamine, dimethylamine, diethylamine, di-n-propylamine, diisopropylamine, di-n-amylamine, diisoamylamine, dihexylamine, diheptylamine, dioctylamine, trimethylamine, triethylamine, tri-n-propylamine, triisopropylamine, tri-n-butylamine, triisobutylamine, tri-sec-butylamine, tri-n-amylamine, ethanolamine, n-propanolamine, isqpropanolamine, di ethanolamine, N,N-diethylethanolamine, N-ethylpropanolamine, N-butylethanolamine, allylamine, nutenyl-2-amine, n-pentenyl-2-amine, 2,3-dimethylbutenyl-2-amine, dibutenyl-2-amine, n-hexenyl- 2amine, propylenediamine, tallowamine, cyclopentylamine, cyclohexylamine, dicyclohexylamine, piperidine, morpholine, and pyrrolidine.

In practice, after several minutes, the ammonium or organic ammonium salt precipitates and can be separated from the solution by any convenient means, as by filtration or centrifugation. Additionally, the reaction mixture may be concentrated, and the remaining solvent removed with hexane, and the residue then dried to recover the ammonium or organic ammonium formula (I) salt.The above reactions may be graphically illustrated as follows:
wherein Rl, R2, X, Y and Z are as described above, and b is the salt forming cation.
When R, and R2 represent different substituents, the carbon to which R, and R2 are attached is an asymmetric center, and the products (as well as their intermediates) exist in d- and /- forms as well as dl-forms.
It should also be understood that the 2-(2-imidazolin-2-yl)pyrindines and quinolines represented by formula (I) in which B=H may be tautomeric, while for convenience, they are depicted by a single structure identified as formula (I), they may exist in either of the isomeric forms illustrated as follows:
wherein A, W, X, Y, Z, R, and R2 are as hereinabove defined and B is H. As such, both isomeric forms of the 2-(imidazolin-2-yl)pyrindines and 2-(2-imidazolin-2-yl)quinolines are meant to be included under the formula (I) definitions.
One general method for the preparation of the formula (I) compounds involves the reaction of a quinolinic anhydride of formula (XVI) hereinbelow, with an appropriately substituted a-aminocarbonitrile of formula (XVII), hereinbelow, to yield a mixture of the monoamides of quinolinic acid of formula (IX) and formula (X).
This reaction is carried out at a temperature between about 20"C and 70"C and preferably between about 35"C and 40"C in an inert solvent, such as tetrahydrofuran, methylene chloride, ether, chloroform, toluene or the like. The thus-formed acids are then cyclized to the corresponding pyrrolopyridine acetonitrile, depicted by formula (XI), by heating the reaction mixture with an excess of acetic anhydride in the presence of a catalytic amount of sodium acetate or potassium acetate.
In general, the above reaction is carried out by treating the reaction mixture with acetic anhydride, acetyl chloride, thionyl chloride or the like and heating said mixture to a temperature between about 20"C and 100 C. Hydration of the thus formed pyrrolopyridine acetonitrile formula (XI) is carried out by treating said acetonitrile with a strong acid such as sulfuric acid. This reaction yields the formula (XII) pyrrolopyridine acetamide. Although the addition of a nonmiscible solvent such as methylene chloride, chloroform or the like is not essential to the conduct of the above described reaction, addition of such a solvent to the reaction mixture is generally preferred. Said reaction is usually carried out at a temperature between about 10 C to 70"C.
The cyclization of the formula (XII), hereinbelow, pyrrolopyridine acetamide yields the tricyclic formula (ill) imidazopyrrolopyridinediones which are intermediates for the imidazolinyl nicotinic acids and esters of the present invention referred to above and represented by formula (Ib).
The product of this reaction is predominantly the desired imidazopyrrolopyridinedione (85%) together with the isomer of formula (Illa). Mixtures of this ratio of the two isomers generally give substantially isomerically pure nicotinate product.
The cyclization reaction is preferably conducted at a temperature of from 80 C to 150"C in the presence of a base such as sodium or potassium hydride or an acid such as an aromatic sulfonic acid and a solvent which will form an azeotropic mixture with water, permitting virtually immediate removal thereof from the reaction mixture as it is formed. Among the solvents which may be employed are toluene, benzene, xylenes and cyclohexane.Based which may be used include alkali metal hydroxides, alkali metal hydrides, alkali metal oxides, tertiary amines such as diisopropyl ethylamine, 1 ,5-diazabicyclo[3.4]nonene-5, 1 ,5-diazobicyclo[5.4.O]undecene-5, 1 ,4-diazabicyclo[2.2.2]octane, tetramethylguanidine, potassium fluoride and quaternary ammonium hydroxide, such as trimethylbenzyl ammonium hydroxide and strongly basic ion exchange resins.
Finally, acidic reagents which can be employed herein include aromatic sulfonic acids, such as ptoluenesulfonic acid, ss-naphthaolenesulfonic acid, naphthalenedisulfonic acid, and the like.
The mixture of compounds of formula (III) and formula (Illa) is then converted to formula (Ib), as discussed above, with an alkali metal alkoxide and alcohol.

Another general method for the preparation of the formula (I) pyridine derivatives involves the reaction of a quinolinic anhydride of formula (XVI), with an appropriately substituted a-aminocarboxylic acid such as a-methylvaline represented by formula (XIX), preferably in a ketonic solvent such as acetone under a blanket of nitrogen to yield an isomeric mixture of the formula (XX) and formula (XXI) acids. The mixture is then treated with acetic anhydride and a catalytic amount of sodium acetate at an elevated temperature to give the dihydrodioxopyrrolopyridine acid formula (XXII).Reaction of the thus-formed acid with a thionyl halide, such as thionyl chloride or thionyl bromide, in the presence of an organic solvent such as toluene, xylene, benzene or the like, at an elevated temperature, i.e., 80"C to 150 C, gives the formula (XXIII) acid halide corresponding to the formula (XXII) acid. Treatment of this acid halide with excess ammonia then yields the formula (IV) dihydrodioxopyrrolopyridine acetamide. The reaction is preferably carried out in the presence of an aprotic solvent.
Reaction of the formula (IV) acetamide with 1,8-diazabicyclo[5,4,0]undec-7-ene in an inert organic solvent such as toluene or xylene at an elevated temperature between about 80"C and 125"C gives the formula (III) imidazopyrrolopyridinedione which may be heated with morpholine or an appropriate NH2R6 amine to yield the 2-(2-imidazolin-2-yl)nicotinamides. These reactions are illustrated as Flow Diagram II.

As described and graphically illustrated in Flow Diagrams I and II above, quinolinic anhydrides of formula (XVI) are used in the preparation of the herbicidally-effective formula (I) 2-(2-imidazolin-2-yl)pyrindine and quinoline compounds.While said quinolinic anhydrides can be prepared by any of the several synthetic routes described in the chemical literature, a particularly effective method of synthesis of these compounds involves reaction of an appropriate formula (LXXI) acetylenic ketone having the structure: Z-CO-C#CH, wherein Z is hydrogen, C1-C6 alkyl or phenyl optionally substituted with C1-C4 alkyl, halogen, C1-C4 alkoxy, nitro, or C1-C4 alkylthio; with an appropriate formula (LXXII) aminomaleate having the structure:
wherein Q is C1-C4 alkoxy; or an appropriate formula (LXXIII) aminofumarate having the structure:
wherein 0 is C1-C4 alkoxy.The ratio of acetylenic ketone to aminoaleate or aminofumarate is preferably about 1:1 and the reaction is generally carried out in a polar solvent such as dimethylformamide (DMF), acetonitrile or a C1-C4 alcohol, preferably ethanol, at a temperature between about 50 and 100 C. This reaction yields the 6-substituted-2,3-pyridinedicarboxylic acid diester of formula (LXXIV).
The formula (LXXIV) diester may then be hydrolyzed to the corresponding 6-substituted-2,3
pyridinedicarboxylic acid by reaction thereof with a strong base such as potassium hydroxide or
sodium hydroxide at a temperature between about 30 and 100"C, preferably in the presence of
a water miscible solvent such as methanol or ethanol. The reaction mixture is then cooled and
treated with a strong mineral acid, such as sulfuric acid. The reaction mixture is then treated
with a ketonic solvent such as acetone and solid sodium sulfate, filtered and the filtrate concen
trated. The remaining residue is triturated with ether, and the formula (LXXV) recovered.Treat
ment of the formula (LXXV) 6-substituted-2,3-pyridinedicarboxylic acid with, for example, acetic
anhydride in the presence of dimethoxyethane and pyridine yields the desired 6-substituted-2,3pyridinedicarboxylic acid anhydride of formula (XVI). This reaction is graphically illustrated in Flow

It has also been found that heating the formula (LXXIII) aminofumarate with an equivalent amount of 2-formylcyclohexanone at a temperature between about 100" and 200"C will yield the dialkyl 5,6,7 ,8-tetrahydroquinoline-2,3-dicarboxylate of formula (LXXVI). This reaction may be illustrated as follows:
herein Q is C,-C4 alkoxy. The thus-formed diester can then be converted to the corresponding diacid by heating with strong base and thereafter acidifying the reaction mixture with a strong mineral acid, such as sulfuric acid.The thus-formed diacid can then be reacted with acetic anhydride, dimethoxyethane and pyridine to obtain the pyridine-2,3-dicarboxylic acid anhydride.
Reaction of the formula (LXXIII) aminofumarate with 4-dimethylamino-3-methyl-3-buten-2-one in the presence of acetic acid, at a temperature between about 50 and 100"C, yields the 5,6 dimethylpyridine-2,3-dicarboxylic acid dimethyl ester which can be hydrolyzed to the corresponding acid by the procedure described in Flow Diagram Il-A above. The diacid is then readily converted to corresponding 5,6-dimethyl quinolinic anhydride of formula (XVI) using, for example, acetic anhydride pyridine and dimethoxyethane as described above.
A preferred method for preparing the 2-(5,5-disubstituted-4-oxo (or thioxo)-2-imidazolin-2-yl)nicotinic acids and 3-quinolinecarboxylic acids involves: the reaction of an appropriately substituted formula (XVI) quinolinic anhydride with an aminocarboxamide or aminothiocarboxamide depicted by formula (Xllla) to yield an isomeric mixture of the formula (XVa) carbamoylnicotinic or 3quinolinecarboxylic acid and formula (XVb) carbamoylpicolinic or quinaldic acid.This reaction is carried out, preferably using equivalent amounts of the anhydride and carboxamide or thiocarboxamide, in the presence of an inert organic solvent such as a low-boiling ether (diethyl ether, tetrahydrofuran, dimethoxyethane), acetonitrile, ethyl acetate or a halogenated hydrocarbon; at a temperature between about 20 and 60"C and preferably 25 to 30"C, under a blanket of inert gas such as nitrogen.When the reaction is essentially complete, the product is isolated by any convenient means, e.g., filtration, distillation of the solvent or by extraction into aqueous base if the solvent is water-immiscible; giving the isomeric pyridine monoacid/monoamide products or the isomeric quinoline monoacid/monoamide products shown as formula (XVa) and formula (XVb) in Flow Diagram Il-B.
The thus-formed mixture is then heated to a temperature of from 25 to about 110"C (i.e., reflux temperature) with about 2 to 10 molar equivalents of aqueous or aqueous alcoholic sodium or potassium hydroxide, preferably under a blanket of inert gas such as nitrogen. The mixture is cooled to about 25"C and acidified to pH 2 to 4 with a strong mineral acid such as hydrochloric acid or sulfuric acid to give the herbicidal product. If the product is insoluble in water, it will precipitate from the aqueous phase and can be recovered by filtration or extraction.
If the product is soluble in water, the mixture can be extracted with an organic solvent such as ether or methylene chloride, and the extract concentrated to provide the herbicidally effective 2 (5,5-disubstituted-4-oxo-(or thiono)-2-imidazolin-2-yl)nicotinic or 3-quinolinecarboxylic acids, encompassed by formula (I).

In another general procedure, the 2-(2-imidazolin-2-yl)pyridine acids and esters of formula (I), can be prepared by reacting the 2-carboalkoxynicotinoyl chloride of formula (XIV), hereinbelow, preferably as the methyl ester and preferably in the form of the hydrochloride salt, with the appropriate aminocarboxamide depicted by formula (XIII). The reaction yields the carbamoyl picolinate, formula (XV), and is preferably carried out in an inert blanket of gas such as nitrogen.
The reaction mixture is generally maintained at a temperature below 30"C during the reaction period.
The thus-formed carbamoyl picolinate, formula (XV), hereinbelow, can then be dispersed in an inert non-protic solvent such as xylene or toluene and heated to about 50"C tio 130"C with 1,5 diazabicyclo-[5.4.0]undec-5-ene. The reaction yields a mixture of the formula (III) and formula (Illa), imidazopyrrolopyridinedione isomers which can be used without separation in the following reaction, wherein the reaction mixture is treated with an alkali metal alkoxide, in the presence of an alcohol to yield a mixture of the imidazolinyl nicotinate and the imidazolinyl picolinate. The desired formula (Ib) nicotinate can be readily separated from the picolinate by neutralizing the reaction mixture, preferably with glacial acetic acid, concentrating the neutralized solution and chromatographing the resulting residue on silica gel in ether.
Conversion of the imidazolinyl nicotinate esters to the corresponding acids or acid addition salts can be readily achieved by the methods previously described. Similarly, the imidazolinyl nicotinic acids can be converted to the corresponding alkali metal, ammonium, or organic ammonium salts by the methods previously described.

Advantageously, many of the formula (II) 2-(2-imidazolin-2-yl)quinoline derivatives of the present invention can be prepared by the procedures described above for the preparation of the formula (I) 2-(2-imidazolin-2-yl)pyrindine compounds. For example, the formula (XXXVI) 2-(2imidazolin-2-yl)quinolinecarboxylate esters, wherein Ra represents a substituent other than hydrogen or a salt-forming cation, and Rl, R2, X, L, M, Q and R7 are as described above, can be prepared by reacting the formula (XXXVII) dione, with an appropriate alcohol and alkali metal alkoxide at a temperature between about 20 C and 50 C.In these reactions, as with similar reactions in which the formula (I) pyridines are prepared, the alcohol can function both as a reactant and a solvent. As such, a secondary solvent is not required, but can be employed if so desired. When a secondary solvent is used, it is preferably to employ a non-protic solvent such as tetrahydrofuran or dioxane.The reaction may be illustrated as follows:
where M is an alkali metal; X is hydrogen, halogen, hydroxyl or methyl, with the proviso that when one of L, M, Q or R, is a substitutent other than hydrogen, halogen, C1-C6 alkyl, or C1-C4 alkoxy, X is hydrogen; L, M, 0 and R7 each represent members selected from the group consisting of hydrogen, halogen, C1-C4 alkyl, C4C4 alkoxy, C,-C4 alkylthio, C,-C4 alkylsulfonyl,
C,-C4 haloalkyl, NO2, CN, phenyl, phenoxy, amino, C,-C4 alkylamino, diloweralkylamino, chlorophenyl, methylphenyl or phenoxy substituted with one Cl, CFa, NO2 or CH2 group, with the proviso that only one of L, M, O, or R7 may represent a substituent other than hydrogen, halogen, Cl-C4 alkyl or Cl-C4 alkoxy, and R1, R2 and R2 are as described above.
The formula (XXXVI) 2-(2-imidazolin-2-yl)quinoline-carboxylate esters can also be prepared from a formula (XXXVIII) dioxypyrroloquinoline acetamide, wherein R1, R2, X, L, M, Q and R7 are as described above, by cyclization thereof with a strong base, such as 1,5-diazabicyclo[5.4.0]un- dec-5-ene (DBU) in the presence of an inert organic solvent such as xylene or toiuene to give the crude imidazopyrroloquinolinedione of forula (XXXVII). The reaction mixture is heated to a temperature between 1 000C and 150 C, and water removed from the reaction mixture using a
Dean-Stark water separator.At least one equivalent of alcohol RaOH represented by formula (V); wherein Ra is a substituent as described above, but excluding hydrogen and salt-forming cations, is then added to the reaction mixture, and the thus prepared mixture heated to reflux at a temperature between 1 000C and 150"C to yield the formula (XXXVI) ester. The reaction may be graphically illustrated as follows:
wherein R1, R2, Ra, X, L, M, Q and R7 are as described above.
The formula (XXXVI) 2-(2-imidazolin-2-yl)quinoline-carboxylate esters can also be prepared by cyclization of a carbamoyl quinolinecarboxylate ester, represented by formula (XXXIX), with phosphorus pentachloride at an elevated temperature between about 60"C and 100"C. The reaction is generally conducted in the presence of an inert organic solvent, such as toluene or benzene, and yields and hydrochloride salt of the formula (XXXVI) 2-(2-imidazolin-2-yl)quinolinecarboxylate ester. Treatment of the thus formed hydrohalide salt with base, such as sodium or potassium carbonate, then yeids the formula (XXXVI) 2-(2-imidazolin-2-yl)quinolinecarboxylate ester.The carbamoyl quinolinecarboxylate ester, formula (XXXIX), used in the above reaction may be shown as follows:
wherein Ra is a substituent as described above, but excluding hydrogen or a salt-forming cation and R1, R2, X, L, M, Q and R7 are as described above.
The 2-(2-imidazolin-2-yl)quinolinecarboxylate esters of formula (XXXVI) are also formed by cylization of the carbamoyl quinolinecarboxylate esters represented by formula (XXXIX), and having the structure:
wherein R2is as described above excepting that hydrogen and salt-forming cations are excluded and R1, R2, X, L, M, Q and R7 are as described above. Cyclization of the carbamoyl quinolinecarboxylate ester is achieved by reaction thereof with a mixture of phosphorus pentachloride and phosphorus oxychloride. The reaction mixture is stirred for several hours at a temperature between about 15"C and 35"C, and the POCK, then removed in vacuo. The residue from this treatment is dispersed in an organic solvent such as toluene.The solvent is then separated from the resulting mixture, and the remaining residue dispersed in water heated to between 80"C and 100"C. After cooling, the pH of the aqueous mixture is adjusted to 5-6 with sodium or potassium bicarbonate, and the product extracted into methylene chloride to give the 2-(2imidazolin-2-yl)quinolinecarboxylate ester, formula (XXXVI).
The formula (XXXVI) quinoline ester in which Ra is as described above, but excluding hydrogen or salt-forming cations, and R1, Rz, X, L, M, Q and R7 are as described above, is readily converted to its corresponding acid addition salt by reaction of said ester with at least one equivalent of a strong acid. Strong mineral acids such as hydrochloric acid, sulfuric acid, and hydrobromic acid are employed although organic acids may also be used. In practice, it is also found that the reaction proceeds most satisfactorily when conducted in the presence of an inert organic solvent such as ether, chloroform, methylene, chloride, or mixtures thereof. Sulfuric acid salts are generally prepared by this procedure, but substituting a lower aliphatic alcohol for the above-mentioned solvents.
Preparation of the formula (II) 2-(2-imidazolin-2-yl)quinoline derivatives wherein A is COOH: B is hydrogen; W is oxygen and R1, R2, X, L, M, Q and R7 are as defined, with the proviso that X, L,
M, Q and R7 are not halogen or nitro, can be achieved by hydrogenolysis of the benzyl ester of the formula (XXXVI) 2-(2-imidazolin-2-yl)quinolinecarboxylate. The reaction involves dispersion of the benzyl ester in an organic solvent, such as described above for the hydrogenolysis of the formula (XV) benzyl ester in the 2-(2-imidazolin-2-yl)pyrindine series, and treatment of the thusprepared reaction mixture with hydrogen gas in the presence of a catalyst such as palladium or platinum on a carbon carrier.The hydrogenolysis is generally carried out at a temperature between about 20"C and 50"C.
The acids of the formula (II) 2-(2-imidazolin-2-yl)quinoline derivatives in which A is COOH; B is hydrogen; W is oxygen and R1, R2, X, L, M, Q and R7 are as described above, are also prepared by reaction of a formula (XXXVI) ester, in which Ra is a substituent as described above, but excluding hydrogen and salt-forming cations and R, R2, X, L, M, Q and R7 are as described, with at least one equivalent of strong aqueous base, such as an aqueous solution of an alkali metal hydroxide, at a temperature between 20 C and 50 C. The mixture is cooled and then adjusted to pH 6.5 to 7.5 with a strong mineral acid. Such treatment yields the desired acid.
Preparation of the formula (II) 2-(2-imidazolin-2-yl)quinoline derivatives in which A is COPRA; R2 is a salt-forming cation; B is hydrogen; W is oxygen and R1, R2, L, M, Q and R7 are as described above, can be prepared by dissolving an acid, represented by formula (II) wherein A is COOH; B is hydrogen; W is oxygen and R1, R2, L, M, Q and R7 are as described above, in an appropriate solvent and treating the thus prepared mixture with at least one equivalent of a salt-forming cation. The reaction is essentially the same as described for the preparation of the formula (I) pyridines in which A is COOT, and R2 is a salt-forming cation.
It should also be understood that the imidazolinylquinolinecarboxylic acids and esters depicted by formula (II) in which B is H may be tautomeric.
It should also be understood that when R1 and R2 represent different substituents on the formula (II) 2-(2-imidazolin-2-yl)quinoline derivatives and the formula (XXXVII) imidazopyrroloquinolinediones, the carbon to which R1 and R2 are attached is an asymmetric center, and the products (as well as their intermediates) exist in d- and I- forms as well as dl forms.
Cyclization of the formula (XXXVIII) imidazopyrroloquinoline acetamide yields the tetracyclic formula (XXXVII) and formula (XXXVlla) imidazopyrroloquinolinediones which are intermediates for the formula (II) 2-(2-imidazolin-2-yl)quinolinecarboxylate acids and esters.
The product of this reaction is predominately the desired imidazopyrroloquinolinedione together with a small amount of the formula (XXXVlla) isomer. Treatment of the isomeric mixture with an alkali metal alkoxide gives substantially isomerically pure quinolinecarboxylate product.
The cyclization reaction is preferably conducted at a temperature of from 80"C to 150"C in the presence of a base such as sodium or potassium hydride or an acid such as an aromatic sulfonic acid and a solvent which will form an azeotropic mixture with water, permitting virtually immediate removal thereof from the reaction mixture as it is formed. Among the solvents which may be employed are toluene, benzene, xylenes and cyclohexane.Bases which may be used include alkali metal hydroxides, alkali metal hydrides, alkali metal oxides, tertiary amines such as diisopropyl ethylamine, 1 ,5-diazabicyclo[3.4]nonene-5, 1 ,5-diazobicyclo[5 .4.0]undecene-5, 1 ,4-diazabicyclo[2.2.2]octane, tetramethylguanidine, potassium fluoride and quaternary ammonium hydroxide, such as trimethylbenzyl ammonium hydroxide and strongly basic ion exchange resins.
Finally, acidic reagents which can be employed herein include aromatic sulfonic acids, such as Thtoluenesulfonic acid, ssnaphthalenesulfonic acid, naphthalenedisulfonic acid, and the like.

Several routes are employed to prepare pyrroloquinoline acetamides represented by formula (XXXVIII). Preferably hydration of the pyrroloquinoline acetonitrile of formula (XXXX) is accomplished by treatment with a strong acid such as sulfuric acid. This reaction yields the formula (XXXVIII) pyrroloquinoline acetamide. Although the addition of a non-miscible solvent such as methylene chloride, chloroform or the like is not essential to the conduct of the above described reaction, addition of such a solvent to the reaction mixture may be preferred. Said reaction is usually carried out at a temperature between 10 C to 70 C.
Alternatively, the pyrroloquinoline acetamide of formula (XXXVIII) may be obtained by the Diels-Aider cycloaddition reaction between substituted anthranils of formula (XXXXI) and the dioxopyrroline acetamide of formula (XXXXII). These reactions are carried out in a wide temperature range: below 1300C significant amounts of the intermediate aldehyde of formula (XXXXIII) are obtained, but at 1300C-2000C the pyrroloquinoline acetamide of formula (XXX-VIII) is formed.
Alternatively, the intermediate aldehyde of formula (XXXXIII) may be isolated and cyclized in refluxing xylene in the presence of an acid catalyst, such as ptoluene sulfonic acid. This reaction yields the desired formula (XXXVIII) pyrroloquinoline acetamide. These reactions may be graphically illustrated as shown below on Flow Diagram V.

A variety of routes may also be employed to obtain the formula (XXXX) pyrroloquinoline acetonitriles depending on the nature of the L, M, Q and R7 substituents.
The formula (XXXX) pyrroloquinoline acetonitriles may be prepared by reacting the appropriately substituted anhydride (XXXXIV) with an appropriately substituted a-aminocarbonitrile of formula- (XVII), to yield a mixture of the monoamides of the formula (XXXXVa) and formula (XXXXV b) acids.
This reaction is carried out at a temperature between 20 C and 70 C and preferably between about 35 C and 40 C in an inert solvent, such as tetrahydrofuran, methylene chloride, ether, chloroform, toluene or the like. The thus-formed acids are then cyclized to the corresponding pyrroloquinoline acetonitrile, depicted by formula (XXXX). This is accomplished by heating the reaction mixture to a temperature between about 75 C and 150 C with an excess of acetic anhydride in the presence of a catalytic amount of sodium acetate or potassium acetate.
In general, the above reaction is carried out by treating the reaction mixture with acetic anhydride, acetyl chloride, thionyl chloride or the like, and heating said mixture to a temperature between about 20 C and 100 C. The above reactions are illustrated graphically on Flow Diagram

A preferred route to pyrroloquinoline acetonitrile of formula (XXXX) is the Diels-Alder thermal cycloaddition reaction of an appropriately substituted maleimide of formula (XXXXVI) with an appropriately substituted anthranil. In this route X must be hydrogen.
The outcome of this reaction is dependent upon the reaction temperature. Intermediate of formula (XXXXVII) is obtained at -55 C. As the reaction mixture is heated further, to temperatures between 55 C and 130 C, the intermediate of formula (XXXXIII) aldehyde is obtained. If the reaction is conducted in the presence of an aprotic solvent such as o-dichlorobenzene, and the reaction mixture heated to between 140 C and 200 C, the reaction yields the pyrroloquinoline acetonitrile of formula (XXXX). The reaction is illustrated on Flow Diagram VII below.
FLOW DIAGRAM VII
The above route is particularly effective when L, M, 0 and R7 groups are electronegative, e.g., halogens, nitro, CF3, SO2CH3, CN.
A variation of this procedure involves the reaction of an o-aminoacetal of formula (XXXXVIII) with an appropriately substituted formula (XXXXX) maleimide or dioxopyrroline acetamide, in the presence of an aprotic solvent such as xylene or toluene at a temperature between about 50 C and 130 C. These reactions are graphically illustrated below.
Yet a further variation, useful for synthesis from anilines bearing electron donor substitution in the L, M, Q and R7, positions or one halogen or CF2 function, is the interaction of o-alkyl or arylthiomethylanilines formula (XXXXIX) with a bromomaleimide of formula (XXXXX) to give the maleimide of formula (XXXXXI) which is oxidized to the maleimide of formula (XXXXXII). The meleimide of formula (XXXXXII) is then cyclized in an acid catalyzed reaction to yield the pyrroloquinoline acetonitrile of formula (XXXX). The reactions are graphically illustrated below.
R1, R2, L, M, Q and R7 are as defind above.
Compounds of formula (XXXX) bearing electron donor substitution on th L, M, Q and R7 positions, such as alkyl, alkoxy, alkylthio, dialkylamino, hydroxy and a single halogen may be prepared by reaction of an appropriately substituted o-aminobenzyl alcohol of formula (XXXXXIII) or anthranilic acid of formula (XXXXXIV) with a bromo(or chloro)maleimide of formula (XXXXX).
This reaction is conducted in the presence of a protic solvent, such as isopropyl or tbutylalcohol at O"C to 30"C to yield respectively, the hydroxymethylanilinemaleimide of formula (XXXXXV) or dioxopyrrolinyl anthranilic acid of formula (XXXXXVI). A variety of base acceptors can be employed in the above reactions, e.g., alkaline earth metal hydroxides, such as Ba(OH)2,
BaO or sodium acetate. However, the reactions in many instances proceed satisfactorily without the aid of the base acceptor.
Oxidation of the formula (XXXXXV) alcohol to the formula (XXXXIII) aldehyde may be accomplished using a wide variety of oxidizing agents exemplified by pyridinium-chlorochromate in methylene chloride or activated manganese dioxide in t-butanol. Cyclization of the aldehyde of formula (XXXXIII) to the pyrroloquinoline acetonitrile of formula (XXXX) is achieved by one of the methods described above, such as heating said aldehyde to between 140 C and 200"C in the presence of an aprotic solvent.
Cyclization of the o-anilinocarboxylic acid of formula (XXXXXVI) to the acetoxyquinoline of formula (XXXXXVII) is accomplished with acetic anhydride, triethylamine and 4-dimethylaminopy ridine at ambient temperatures. Mild reductive elimination gives the pyrroloquinoline acetonitrile of formula (XXXX). Hydrolysis in warm aqueous acetic acid gives formula (XXXX) where X=OH, further reaction with phosphorus oxychloride and pyridine, affords compounds where X is chlorine. These reactions are illustrated in Flow Diagram VIII below.

FLOW DIAGRAM VIII (CONTINUED)
Another route to the 2-(2-imidazolin-2-yl)quinoline compounds of formula (II), particularly useful in synthesizing analogs in which the A group is varied, employs the 2-(2-imidazolin-2-yl)quinoline of formula (XXXXXIX). This intermediate is prepared from quinolinecarboxylic acid of formula (XXXXXVIII) which is converted to the acid chloride or anhydride and then reacted with either an appropriately substituted a-aminocarbonitrile of formula (XVI I) to give the formula (XXXXXX) nitrile, or with the aminoamide of formula (XXXXXXI) to give the carboxamidoamide of formula (XXXXXXII). Cyclization of said carboxamidoamide is accomplished by the previously discussed procedures, although cyclization with sodium hydride in the presence of xylene is preferred.
Introduction of a variety of groups, A, is made possible by treatment of the 2-(2-imidazolin-2y!)quinoline of formula (XXXXXIX) with metallating reagents. Most organo metallic agents have some effect when two moles are used with the formation of a dianion, but the yield and reaction composition is dependent upon the nature of the organometallic reagent, reaction solvent, reaction temperature and the electrophile used to quench the reaction. In practice organometallic reagents such as alkyl lithiums are preferred and anion formation is obtained with methyl, n-butyl, sec-butyi and tert-butyl lithium. Phenyl lithium and lithium diisopropylamide may also be employed. Solvents must be aprotic and diethylether is preferred.Reaction temperatures employed to form the dianion range from-780C to 0 C with -30 C to - 100C preferred.
Quenching with an electrophile is usually accomplished at -78 C to +20 C. If necessary, this is followed by acid treatment. All reactions are run under an inert atmosphere. Examples of reactive electrophiles include: CO2, CICO2CH2, (CHa)2NCHO, CH3HNO, C6HsCHO, CHal. The corresponding values for A in formula (IIa) are COOH, COOCH3, CHO, CH(OH)CH3, CH(OH)C6Hs, CH3.
Furthermore, following the quenching of the electrophile, the products may be modified. Thus the aldehyde (A=CHO) prepared from a DMF quench, reacts with hydroxylamine to afford an oxime. The above route is also useful for the synthesis of A=COOH compounds by treatment of the dianion with carbon dioxide.
Not all X, L, M, 0 and R7, substituents are compatible with this organometallic process. Thus, if the above mentioned substituents are Br, I or sometimes fluorine, competitive loss of these groups occurs as well as replacement of the 3-proton of quinoline. Chlorine, however, is compatible with this process. When L, M, Q or R7, is methoxy, competitive anion formation can occur ortho to the methoxy group.
The above-described reactions are graphically illustrated on Flow Diagram IX below.
FLOW GR tA
Several functional groups, A, are prepared by an alternative approach. Thus reaction of the 'imidazopyrroloquinolinedione of formula (XXXVII) with RaOM affords the 2-(2-imidazolin-2-yl)qui -noline esters of formula (XXXVI). In the case of formula (II) compounds in which A is the CONHCH2CH2OH group, this may be cyclized to the oxazoline group via reaction of the above
identified compound with triethylphosphite in refluxing xylene. Formula (II) derivatives, in which A
is -CONH2, may be converted to the corresponding cyano derivative, i.e., A=CN, by dehydration
of the -CONH2 function.
The majority of compounds containing L, M, 0, and R7 substituents may be prepared by the
procedures previously outlined; however, amino, alkylamino, and dialkylamino compounds are
conveniently formed by reductive alkylation of the appropriate nitro substituent in the L, M, O, or
R7 position. Alkylsulfonyl compounds are most readily formed by mild oxidation of the alkylsulfo
nyl group in the L, M, O, or R7 position at 0 C-20 C using m-chloroperbenzoic acid. Under these
conditions, N-oxidation of the quinoline nitrogen is minimized.
Oxidation of the quinoline to the N-oxide can be accomplished by prior N-protection of the
imidazolone ring with, e.g., a COUCH, group; N-oxidation can now be accomplished by peracetic
acid or trifluoroperacetic acid, at elevated temperatures, if necessary.
Preparation of 2-(2-imidazolin-2-yl)-3-quinolinecarboxylic acids, i.e., formula (II) compounds
where A is COOH, can also be prepared by a rather unique procedure involving the reaction of
an appropriately substituted formula (LXXVII) aniline wherein L, M, 0, and R7 are as described
above, with a keto-ester depicted as formula (LXXVIII) wherein R' is CH2 or CO2R" and R" is Ca-C4 alkyl. This reaction is optionally conducted in the presence of an organic acid such as P toluenesulfonic acid hydrate in the presence of an organic solvent such as toluene, xylene,
benzene, or the like, at a temperature of from about 20 to 110 C, preferably 100" to 110 C.
The reaction yields the fi-anilino-a,fl-unsaturated ester of formula (LXXIX). The thus-formed ss anilino-a,ss-unsaturated ester of formula (LXXIX) is then reacted with an immonium salt depicted
by formula 0+ e Cl-CH=N-(R"')2 C I (LXXX) wherein R"' is C1-C6 alkyl or e Cl-CH= N (CH2)n' CI n' is 4 or 5, in the presence of a low boiling
chlorinated hydrocarbon solvent such as methylene chloride or dichloroethane at a temperature
between about 40 and 90 C, for a period of time sufficient to essentially complete the reaction
and yield the formula (LXXXI) alkyl ester of 2-methyl-3-quinolinecarboxylic acid when R' is methyl
or the dialkyl ester of quinoline-2,3-dicarboxylic acid when R' is COOR".
Alternatively, the formula (LXXVII) substituted aniline, wherein L, M, Q, and R7 are as de
scribed above, can be reacted with an acetylene dicarboxylate of the structure shown as formula
(LXXXII) wherein R" is C,-C4 alkyl. This reaction is generally carried out in the presence of
solvent such as dichloroethane or a C,-C4 alcohol such as methanol, at a temperature between 0" and 100"C, to yield a ssanilino-a,ss-unsaturated ester shown as formula (LXXXIII). The ss anilino-a-p-unsaturated ester of formula (LXXXIII) is then reacted with an immonium salt depicted
by formula (LXXX).This reaction is generally carried out in the presence of a low-boiling solvent
such as methylene chloride or dichloroethane at a temperature between 40 and 90"C for a
period of time sufficient to complete the reaction and yield the quinoline-2,3-dicarboxylate shown
as formula (LXXXIV) wherein L, M, O, R7, and R" are as described above.
The immonium salt formula (LXXX) utilized in the above cyclization reactions may thereinafter,
be referred to as the Vilsmeier reagent. This reagent may be generated from a formamide (alkyl
or phenyl) reaction with PODIA, COCI2, CICO-COCI, or SOCI2 in a chlorinated hydrocarbon solvent.
While the anion in formula (LXXX) is shown as CI", it should be recognized that when POCl3 is -used to prepare the Vilsmeier reagent, the anion is PO2C1t2.
Conversion of the formula (LXXXI) alkyl ester of 2-methyl-3-quinolinecarboxylic acid, to the
2,3-quinolinedicarboxylic acid of formula (LXXXV) is achieved by a very distinctive process
involving the simultaneous oxidation of the R' methyl function and the hydrolysis of the ester function R" of the alkyl ester of 2-methyl-3-quinolinecarboxylic acid. This is accomplished by
admixing the formula (LXXXI) alkyl ester of 2-methyl-3-quinolinecarboxylic acid with a sufficient
amount of water to give a 0.02 to 1.0 M solution of said compound and adding thereto about
5-15% by weight of aqueous alkali metal hydroxide such as sodium or potassium hydroxide.
The mixture is stirred to provide an essentially homogeneous mixture. In practice, it has been
found beneficial, although not essential, for the formula (LXXXI) starting material to have some ;solubility in the reaction medium, either initially or after saponification of the functional group R'.
The reaction mixture is then treated with from 3.0 to 4.0 molar equivalents (preferably up to 1
molar equivalent excess) of nickel peroxide. Addition of the nickel peroxide to the mixture can
be made in small increments or all at once. However, the temperature of the reaction mixture
should be maintained at from 0 to 30 C, and the mixture should be stirred until the oxidation
and hydrolysis are essentially complete. At the end of the reaction time, no starting material is
detectable, and the insoluble inorganic materials are removed by decantation, filtration, or the
like.The filtrate is then acidified to pH 2 with hydrochloric acid to give the formula (LXXXV)
quinoline-2,3-dicarboxylic acid wherein L, M, O, R7, are as described above, excepting that they
may not represent C1-C4 alkylthio, amino, C,-C4 alkylamino or diloweralkylamino.
Following isolation, the formula (LXXXV) quinoline-2,3-dicarboxylic acid is heated to about 70" to 95"C with an excess of acetic anhydride to yield the formula (LXXXVI) 2,3-quinolinedicarboxylic acid anhydride. A co-solvent such as pyridine or pyridine-dimethoxyethane may also be used
in this reactionf but is not essential to obtain the desired product.
Reaction of the formula (LXXXVI) 2,3-quinolinedicarboxylic acid anhydride with an aminocar
boxamide or aminothiocarboxamide depicted by formula (LXXXVII) is preferably carried out using
equivalent amounts of the anhydride and carboxamide or thiocarboxamide in the presence of an
inert organic solvent such as tetrahydrofuran, diethyl ether, or the like at a temperature between
about 0" and 30 C. When the reaction is essentially complete, the solvent is evaporated, and
the residue triturated with a solvent such as ethyl acetate to afford an isomeric mixture of the 3
quinolinecarboxylic acid and the quinaldic acid shown, respectively, as formula (LXXXVllla) and formula (LXXXVlllb).
The thus-formed mixture is then heated to a temperature of from 25 to about 110 C with about 2 to 10 molar equivalents of aqueous or aqueous alcoholic sodium or potassium hydrox
ide, preferably under a blanket of inert gas such as nitrogen. The mixture is cooled to about 25"C and acidified to pH 2 to 4 with a strong mineral acid such as hydrochloric acid or sulfuric
acid to give the herbicidally effective 2-(5,5-disubstituted-4-oxo-(or thiono)-2-imidazolin-2-yl)-3
quinolinecarboxylic acids, encompassed by formula (LXXXIX); wherein R, is C,-C4 alkyl; R2 is Ct-C4 alkyl or Ca-C6 cycloalkyl; and when R, and R2 are taken together, they may represent C2-C6 cycloalkyl optionally substituted with methyl, and when R, and R2 are not the same, the
optical isomers thereof; W is O or S; and L, M, 0, and R7 each represent members selected from the group consisting of hydrogen, halogen, C,-C4 haloalkyl, difluoromethoxy, diloweralky
amino, C,-C4 alkylthio nitro, phenyl, phenoxy or monosubstituted phenyl or phenoxy where the
substituent is C,-C4 alkoxy or halogen; with the proviso that only one of L, M, O. or R7 may
represent a substituent other than hydrogen, halogen, C,-C4 alkyl or C,-C4 alkoxy.

The formula (I) and formula (II) 2-(2-imidazolin-2-yl)pyridines and 2-(2-imidazolin-2-yl)quinolines and the formula (III) and formula (XXXVI I), imidazopyrrolopyridinediones and imidazopyrroloquinolinediones of the present invention are exceedingly effective herbicidal agents useful for the control of an exceptionally wide variety of herbaceous and woody annual and perennial monocotyledonous and dicotyledonous plants. Moreover, these compounds are herbicidally effective for controlling weeds indigenous to both dry land and wet land-areas.They are also useful as aquatic herbicides and are unique in their effectiveness in controlling the above-said plants when applied to the foliage thereof or to soil or water containing seeds or other propagating organs of said plants such as tubers, rhizomes or stolons, at rates of from about 0.016 to 4.0 kg/ha, and preferably at rates from about 0.032 to 2.0 kg/ha.
It is, of course, obvious that rates of application above the 4.0 kg/ha level can also be used to effectively kill undesirable plant species; however, rates of application of toxicant above the level necessary to kill the undesirable plants should be avoided since application of excessive amounts of toxicant is costly and serves no useful function in the environment.
Among the plants which may be controlled with the compounds of this invention are: Elatine triandra, Sagittaria pygmaea, Scirpus hotarui, Cyperus serotinus, Eclipta alba, Cyperus di fform is, Rotala indica, Lindernia pyridoria, Echinochloa crus-galli, Digitaria sanguinalis, Setaria viridis, Cyperus rotundas, Convolvulus arvensis, Agropyron repens, Datura stramonium, Alopecurus myosuroides, Ipomoea spp., Sida sponosa, Ambrosia artemisiifolia, Eichhornia crassipes, Xanthium pensylvanicum, Sesbania exaltata, Avena fatua, Abutilon theophrasti, Bromus tectornm, Sorghum halepense, Lolium spp., Panicum dichotomiflorum, Matricaria spp., Amaranthus retroflexus, Cirsium arvense, and Rumex japonicus.
Surprisingly, it has now been found that some of the formula (I) and formula (II) compounds of the invention are selective herbicides when applied to the foliage of plants or to soil containing seeds of said plants at relatively low rates of application, i.e., at from 0.016 to about 2.0 kg per hectare, depending on the compound used and crop treated.
In practice, it has been found that generally the formula (I) 2-(2-imidazolin-2-yl)pyridines are best suited for use as broad spectrum herbicides, whether employed preemergence or postemergence to the locus in which used control is desired. This is not to say, however, that all of the formula (I) pyridins are non-selective. Actually, some of the 2-(2-imidazolin-2-yl)pyridines, particularly the five substituted formula (I) and formula (la), pyridines are selective in leguminous crops, particularly crops such as soybeans. Similarly, it has been found that the formula (I) and (II) 2-(2-imidazolin-2-yl)quinolines are generally selective herbicides, particularly effective for controlling undesirable weeds in the presence of leguminous crops such as soybeans.However, certain of the formula (I) and formula (II) compounds are less selective than others in this series.
It has also been found that several of the formula (I) and formula (II) 2-(2-imidazolin-2yl)pyridines and 2-(2-imidazolin-2-yl)quinolines are effective as defoliants for cotton when applied at rates of application between about 0.016 to 4.0 kg hectare. At rates of application not exceeding about 0.01 kg per hectare, it has also been found that certain of the formula (I) and formula (II) pyridines and quinolines are effective for increasing branching of leguminous crops and affecting early maturation of grains.
The formula (XI) pyrrolopyridine acetonitriles, formula (IV) pyrrolopyridine acetamides formula (XXXX) pyrroloquinoline acetonitriles and formula (XXXVIII) pyrroloquinoline acetamides are useful as intermediates for the preparation of the above-mentioned herbicidal formula (I) and formula (II) 2-(2-imidazolin-2-yl)pyridines and quinolines and the herbicidal formula (III) and formula (XXXVII) imidazopyrrolopyridinediones and imidazopyrroloquinolinediones.
Since the formula (I) and formula (II) imidazolinylpyridine and quinoline derivatives, wherein Ra is a salt-forming cation, are water soluble, these compounds can simply be dispersed in water and applied as a dilute aqueous spray to the foliage of plants or to soil containing propagating organs thereof. These salts also lend themselves to formulation as flowable concentrates.
The formula (I) and formula (II) 2-(2-imidazolin-2-yl)pyridines and quinolines and the formula (Ill) and formula (XXXVII) imidazopyrrolopyridinediones and imidazopyrroloquinolinediones, can also be formulated as wettable powders, flow concentrates, emulsifiable concentrates, granular formulations and the like.
Wettable powders can be prepared by grinding together about 20% to 45% by weight of a finely divided carrier such as kaolin, bentonite, diatomaceous earth, attapulgite, or the like, 45% to 80% by weight of the active compound, 2% to 5% by weight of a dispersing agent such as sodium lignosulfonate, and 2% to 5% by weight of a nonionic surfactant, such as octylphenoxy polyethoxy, ethanol, nonylphenoxy polyethoxy ethanol or the like.
A typical flowable liquid can be prepared by admixing about 40% by weight of the active ingredient with about 2% by weight of a gelling agent such as bentonite, 3% by weight of a dispersing agent such as sodium lignosulfonate, 1% by weight of polyethylene glycol and 54% by weight of water.
A typical emulsifiable concentrate can be prepared by dissolving about 5% to 25% by weight of the active ingredient in about 65% to 90% by weight of N-methylpyrrolidone, isophorone, butyl cellosolve, methylacetate or the like and dispersing therein about 5% to 10% by weight of a nonionic surfactant such as an alkylphenoxy polyethoxy alcohol. This concentrate is dispersed in water for application as a liquid spray.
When the compounds of the invention are to be used as herbicides where soil treatments are involved, the compounds may be prepared and applied as granular products. Preparation of the granular product can be achieved by dissolving the active compound in a solvent such as methylene chloride, N-methylpyrrolidone or the like and spraying the thus prepared solution on a granular carrier such as corncob grits, sand, attapulgite, kaolin or the like.
The granular product thus prepared generally comprises about 3% to 20% by weight of the active ingredient and about 97% to 80% by weight of the granular carrier.
In order to facilitate a further understanding of the invention, the following examples are presented primarily for the purpose of illustrating certain more specific details thereof. The invention is not be be deemed limited thereby except as defined in the claims. Unless otherwise noted, all parts are by weight.

The mixture had reached the boiling point of the solution after about one quarter of the aminonitrile had been added and the rate of addition is adjusted to maintain this temperature. After the addition the solution is heated under reflux for a further 4 hours. The solution is cooled, filtered and concentrated to a thick oil. This oil is dissolved in 950 ml acetic anhydride, 6 g anhydrous sodium acetate added and the mixture distilled until the vapor temperature reached 118"C when the heating was continued under reflux for 3 hours. The mixture is concentrated in vacuo the residue dissolved in 500 ml toluene and again concentrated. This is repeated. The residue is slurried with a mixture of ether and hexane and the crude product which crystallizes collected (349 g). This is dissolved in 700 ml methylene chloride and filtered through a column containing 700 g silica gel and the product eluted with methylene chloride. Concentration of the eluant gave 258 g of the desired product. An analytically pure sample with mp 95-96"C can be obtained by the recrystallization of the product from ether-methylene chloride.

After the addition the temperature is adjusted to 60-65 C and maintained there for 1 1/2 hours. The mixture is cooled, quenched with ice and finally diluted to approximately 4 liters. After adding 454 g sodium acetate and cooling at 0 C for 2 hours the mixture is filtered, the solids collected and washed twice with 500 ml water containing sodium acetate followed by water to remove all the sulfuric acid. The solid is dried to give 289 g of product, mp 176-178 C. Material made in a similar way and analytically pure had mp 188-190 C.

A mixture of 50 g amide and 450 ml toluene is heated under a Dean-Stark water separator to remove traces of water. To the cooled mixture is added 10.1 g of a 50% suspension of sodium hydride in mineral oil and the mixture heated under reflux for 23 hours. The hot solution is filtered, concentrated in vacuo where upon the residue is crystallized. The mineral oil is removed by decantation and the solid washed with hexanes and dried in vacuo to give 45.5 g product which, by nmr analysis, is approximately 90% the desired isomer II and 10% the undesired isomer Ia.
A pure sample of isomer II can be obtained by recrystallizing the crude product from hexanemethylene chloride mp 107-115"C.
The cyclisation can be achieved by either the basic reagent sodium and potassium hydroxide, or the acidic reagent p-toluenesulfonic acid in a toluene solvent. It should be understood that a mixture of products corresponding to Structures II and Ia above is obtained and in general these are not purified but used directly for the preparation of the derived nicotinic acid esters.

bicyclo[5.4.0]-undec-5-ene(DBU) in 400 ml xylene is heated under reflux under a Dean-Stark

graphed on 400 g basic alumina. The mixture of desired products is eluted with methylene
chloride and used without further purification.
EXAMPLE 5
Preparation of Methyl 2-(isopropyl-5-methyl-4-oxo-2-imidazolin-2-yl)nicotinate
To 20 ml dry methanol in which 10 mg sodium hydride had reacted is added 2.0 g of a
mixture of the imidazopyrrolopyridines. After stirring for 16 hours, 0.03 g glacial acetic acid is
added (to neutralize the base), the solution concentrated in vacuo and the residue chromato
graphed on silica gel in ether. The faster moving material, the desired ester, is obtained in I several fractions, combined, concentrated and crystallized from acetonitrile to give the imidazoli
nyl nitotinate, mp 121-123.5"C. An analytically pure sample crystallized from methylene chloride
hexane exhibits a melting point of from 121-122"C.
EXAMPLE 6
Preparation of Methyl 2-(5-isopropyl-5-methyl-4-oxo-2-imidazolin-yl)nicotinate
This method involves the formation of the tricyclic compounds of Example 3 and 4, without
isolation, directly forming the nicotinic acid esters:
A mixture of 25 g amide and 1 ml 1,5-diazabicyclo-[5.4.0]undec-5-ene(DBU) in 500 ml xylene is heated under reflux for 1 hour under a Dean-Stark water separator. The mixture is cooled somewhat, the water separator removed, 100 ml anhydrous methanol added and the mixture heated under reflux for 1 hour. The solvents are then removed in vacuo and the product isolated by chromatography as descrivbed in Example 5 above to give 13.65 g product mp 120-122"C identical to that described in Example 5 above.
EXAMPLE 7
Preparation of Methyl 2-(5-isopropyl 5-methyl-4-oxo-2- imidazolin-2-yl)nicotinate. Method A (Flow
Diagram pg. 7 7) A mixture of 13.65 g of the nicotinate and 9.69 g phosphorus pentachloride in 110 ml dry toluene is heated with stirring to 80"C. After 1 1/2 hours, the thick mixture is cooled, filtered and the solid washed with ether and dried. This is the hydrochloride salt of the desired product.
This salt is dissolved in 60 ml water; neutralized with sodium bicarbonate, the resulting precipitate removed by filtration, washed with water and air-dried to give the product identical to that prepared by the procedure of Example 5.
METHOD B
A mixture of 5.0 g nicotinate and 7.1 g phosphorus pentachloride in 40 ml phosphorus oxychloride is stirred at room temperature overnight. The phosphorous oxychloride is removed in vacua, the residue suspended in 40 ml toluene and again concentrated. This is repeated. Water (40 ml) is added to the residue and the mixture heated to reflux and held there for 1 hour. After cooling, the mixture is extracted with methylene chloride, the extract dried and concentrated to give 1.05 g of the desired product. The pH of the aqueous phase from the methylene chloride extraction is adjusted to 5.6 with sodium bicarbonate solution and the mixture extracted again with methylene chloride.

To a slurry of 1 ,3-dihydro-a-isopropyl-a-methyl-1 ,3-dioxo-2-It-pyrrolo [3,4-b] quinoline-2-acetamide (5.76 g, 0.0185 mol) in dry xylene (600 ml) is added a 50% oil dispersion of sodium hydride (1.33 g, 0.0278 mol) and the mixture is heated to reflux, whereupon the reaction mixture becomes homogeneous. After 3 hours at reflux the reaction is set aside at room temperature overnight and then methanol (15 ml) containing sodium methoxide (0.1 g) is slowly added and warmed at reflux for 1 hour. The mixture is filtered while hot and the organic solvents stripped to give an oil and solid. A methylene chloride-water mixture is shaken with the above residues, until they dissolve. The aqueous layer (200 ml) is separated and slowly acidified with acetic acid (5 ml).A precipitate of the product is formed and is collected by filtration to give 3.91 g (72%) of mp 219-224"C. Recrystallization from hexane-ethyl acetate gives mp 219-222"C (dec.). Anal. calcd. for C,7Hr7N303: C, 65.58; H, 5.50; N, 13.50. Found: C, 65.09; H, 5.50; N, 13.59.
The procedure described above is used to prepare the compounds reported in Table Ill below.
However, to avoid ester formation, rather than filter off the insolubles and strip down the xylene, one may simply add methanol followed by water (caution, hydrogen may be evolved) to the xylene layer.

To an ice-cold-solution of 80 g (+)-tartaric acid in 200 ml water is added 56 g of (+)-2- amino-2,3-dimethylbutyronitrile. During the addition, the mixture is kept cold. The precipitate is collected by filtration, washed with a small amount of ice-cold water and dried to give 65.25 g of the tartrate salt (B).
The filtrate from (B) is treated with 56 ml concentrated ammonia and extracted three times with ether. The combined extracts are washed with brine, dried and concentrated to give 24 g (-)-2-amino-2,3-dimethylbutyronitrile (A) with [a]2D5= -4.49 (c=0.0376 g/ml THF).
The (-)-aminonitrile is converted again to the salt with 39 g (-)-tartaric acid in 54 ml water, the salt collected, and the aminonitrile liberated from the salt with 26 ml concentrated ammonium hydroxide as described above. This process gives 19.3 g of (-)-2-amino-2,3-dimethylbuty- ronitrile with [a]2D5= -5.89 (c=0.0353 g/ml THF).

Preemergence Herbicidal Evaluation of Test Compounds
The preemergence herbicidal activity of the compounds of the present invention is exemplified by the following tests in which the seeds of a variety of monocotyledonous and dicotyledonous
plants are separately mixed with potting soil and planted on top of approximately one inch of
soil in separate pint cups. After planting, the cups are sprayed with the selected aqueous
acetone solution containing test compound in sufficient quantity to provide the equivalent of
about 0.016 to 10 kg per hectare of test compound per cup.The treated cups are then placed
on greenhouse benches, watered and cared for in accordance with conventional greenhouse
procedures. From 4 to 5 weeks after treatment, the tests are terminated and each cup is
examined and rated according to the rating system set forth above. The herbicidal proficiency of
the active ingredients of the present invention is evident from the test results which are
recorded in Table XII below. Where more than one test is involved for a given compound, the
data are averaged.

Evaluation of the defoliation effect of the compounds of the invention on cotton
In the following tests, the appropriate compounds are dissolved or dispersed in acetone-water (1:1) mixtures at the final concentration corresponding to the kg/ha rates indicated in Table XIII below.The solutions also contain 0.1% to 0.25% v/v colloidal BIOFILMS (a product of Colloidal
Products Corp.) which is a mixture of alkyl aryl polyoxyethanol, free and combined fatty acids, glycol ethers, dialkylbenzene carboxyiate and 2-propanol.
The plant species used in these tests is cotton (Gossypium hirsutum, var. Stoneville 213).
The solution or dispersion of the compound under test is sprayed at the rate of 40 ml per pot (one plant per pot) applied to the foliage. The plants are well established seedlings of 4th leaf stage at the time of test.
The pots are watered immediately before treatment. Following treatment, the plants are placed in a random arrangement on greenhouse benches. Normal watering and fertilizing practices are followed (pesticides are applied to plants as needed). Minimum day and night temperatures of 18.3"C are maintained during cooler periods of the year. Normal daily fluctuations occur during the summer season. Plants are sprayed to provide the kg/ha rates indicated in Table XIII below.
Each treatment is replicated six times and the controls 12 times.
The plants are harvested 15 days after the postemergence application of the test solutions and the number of defoliated, dessicated or senescent leaves counted on each plant. Said plarits are also examined for bud growth. Data obtained are reported in Table XIII below, as averages for each treatment.
