BACKGROUND
[0002] The occurrence of undesirable vegetation, e.g., weeds, is a constant problem
facing famers in crops, pasture, and other settings. Weeds compete with crops and
negatively impact crop yield. The use of al herbicides is an important tool in
controlling undesirable vegetation.
There remains a need for new chemical herbicides that offer a broader spectrum
ofweed l, selectivity, minimal crop damage, storage stability, ease of handling, higher
activity against weeds, and/or a means to address herbicide-tolerance that develops with
respect to herbicides tly in use.

undesired vegetation is desired. Methods of application include, but are not limited to, pre-
emergently contacting soil or water, or mergently contacting the rable
vegetation or area adjacent to the undesirable tion.
As used herein, plants and vegetation include, but are not d to, dormant
seeds, germinant seeds, emerging seedlings, plants emerging from vegetative propagules,
immature vegetation, and established vegetation.
As used herein, agriculturally acceptable salts and esters refer to salts and esters
that exhibit herbicidal activity, or that are or can be converted in plants, water, or soil to the
referenced herbicide. Exemplary agriculturally acceptable esters are those that are or can be
hydrolyzed, oxidized, metabolized, or otherwise ted, e.g., in plants, water, or soil, to
the corresponding carboxylic acid which, depending on the pH, may be in the dissociated or
undissociated form.
le salts include those derived from alkali or alkaline earth metals and those
derived from ammonia and amines. Preferred s include sodium, potassium,
magnesium, and aminium cations of the formula:
R13R14R15R16N+
wherein R13, R14, R15 and R16 each, independently represents en or C1-C12 alkyl,
C3-C12 alkenyl, or C3-C12 alkynyl, each of which is optionally substituted by one or more
substituents such as hydroxy, C1-C4 alkoxy, C1-C4 hio, or phenyl groups, provided that
R13, R14, R15 and R16 are sterically compatible. Additionally, any two R13, R14, R15 and R16
together may represent an aliphatic difunctional moiety containing one to twelve carbon
atoms and up to two oxygen or sulfur atoms. Salts of the compounds of Formula (I) can be

hydroxide, with an amine, such as ammonia, trimethylamine, diethanolamine, 2-methyl-
thiopropylamine, bisallylamine, 2-butoxyethylamine, morpholine, cyclododecylamine, or
benzylamine, or with a tetraalkylammonium hydroxide, such as ethylammonium
hydroxide or choline hydroxide. Amine salts of nds of Formula (I) are useful forms
or derivatives of compounds of a (I) because they are water-soluble and lend them-
selves to the preparation of desirable aqueous based herbicidal compositions.
[0013] Other forms or derivatives of compounds of the Formula (I) include N—oxides of
compounds of Formula (I). Pyridine N—oxides can be obtained by ion of the
corresponding pyridines. le oxidation methods are described, for example, in

METHODS OF PREPARING THE COMPOUNDS
Exemplary procedures to synthesize the compounds of Formula (I) are provided
below.
The 3,5-disubstitutedamino(optionally substituted phenyl)picolinic acids of
Formula (I) can be prepared in a number of ways. As depicted in Scheme 1, the 4-amino
picolinates of Formula (II) can be converted to the 4-aminosubstituted-picolinates
of Formula (111), wherein Ar is as herein defined, via Suzuki coupling with a boronic acid or
ester, in the presence of a base, such as potassium fluoride, and a st, such as
bis(triphenylphosphine)-palladium(II) dichloride, in a polar, protic solvent mixture, such as
acetonitrile-water, at a ature, such as 110 CC, 6.g. , in a microwave reactor (reaction
(1;). 4-Aminosubstituted-picolinates of Formula (111) can be transformed into the 5-iodo-
4-aminosubstituted-picolinates of Formula (IV) via a reaction with iodinating reagents,
such as periodic acid and iodine, in a polar, protic t, such as methyl alcohol (reaction
[91). Stille coupling of the aminosubstituted-picolinates of Formula (IV) with a
stannane, such as tetramethyltin, in the presence of a catalyst, such as
bis(triphenylphosphine)-palladium(II) dichloride, in a non-reactive solvent, such as 1,2-
dichloroethane, at a ature, such as 120-130 0C, e.g., in a microwave reactor, provides
-(substituted)aminosubstituted-picolinates of Formula (I-A), wherein Z1 is alkyl,
alkenyl, alkynyl, haloalkenyl and alkylthio (reaction 01).
[00129] Alternatively, 4-aminochloropicolinates of Formula (II) can be ormed
into the 5-iodoaminochloropicolinates of Formula (V) via a reaction with iodinating
reagents, such as periodic acid and iodine, in a polar, protic solvent, such as methyl alcohol
(reaction [92). Stille coupling of the 5-iodoaminochloropicolinates of Formula (V) with
a stannane, such as tetramethyltin, in the presence of a catalyst, such as
bis(triphenylphosphine)-palladium(II) dichloride, in a active solvent, such as 1,2-
dichloroethane, at a temperature, such as 120-130 0C, e.g., in a microwave reactor, provides
-(substituted)aminochloropicolinates of Formula (VI), wherein Z1 is alkyl, alkenyl,
alkynyl, haloalkenyl and hio (reaction Cg). The 5-substitutedamino
picolinates of Formula (VI) can be converted to the 5-substitutedamino
substituted-picolinates of Formula (I-A), n Ar is as herein defined, via Suzuki
coupling with a boronic acid or ester, in the presence of a base, such as potassium fluoride,

[00130] As depicted in Scheme 11, the 4,5,6-trichloropicolinate of Formula (VII) can be
converted to the corresponding isopropyl ester of Formula (VIII), via a reaction with
isopropyl alcohol and concentrated sulfuric acid, 6.g. , at reflux temperature under Dean-
Stark conditions (reaction d). The isopropyl ester of a (VIII) can be reacted with a
fluoride ion source, such as cesium fluoride, in a polar, aprotic solvent, such as dimethyl
sulfoxide (DMSO), at a temperature, such as 80 CC, under Dean-Stark conditions, to yield
the isopropyl trifluoropicolinate of a (IX) (reaction 6). The isopropyl 4,5,6-
trifluoropicolinate of Formula (IX) can be aminated with a nitrogen source, such as
ammonia, in a polar, aprotic solvent, such as DMSO, to produce a 4-amino-5,6-
difluoropicolinate of Formula (X) (reactionf). The fluoro substituent in the 6-position of the
4-amino-5,6-difluoropicolinate of Formula (X) can be exchanged with a chloro substituent
by ent with a chloride source, such as hydrogen chloride, e.g., in dioxane, in a Parr
reactor, at a temperature, such as 100 CC, to produce a 4-aminofluorochloro-picolinate
of Formula (XI) (reaction g). The 4-aminofluorochloropicolinate of Formula (XI) can
be transesterified to the corresponding methyl ester of Formula (XII) by reaction with
titanium(IV) isopropoxide in methyl alcohol at reflux temperature (reaction h).

Example A. Evaluation of Postemergent Herbicidal Activity
Post-Emergent Test 1: Seeds of test species were obtained from commercial
suppliers and planted into a 13 centimeter (cm) er-round pot containing soil-less
media mix (Metro-Mix 360®, Sun Gro ulture). Postemergence treatments were
planted 8-12 days (d) prior to application and cultured in a greenhouse equipped with
supplemental light sources to provide a 16 hour (h) photoperiod at 24—29 °C. All pots were
surface irrigated.
[00356] A weighted , determined by the highest rate to be tested, of each
compound was dissolved in 1.3 mL acetone-dimethyl sulfoxide (DMSO; 97:3, volume per
volume (v/v)) and diluted with 4.1 mL water-isopropanol-crop oil concentrate :2,
v/v/v) containing 0.02% Triton X-lSS to obtain concentrated stock solutions. Additional
application rates were obtained by serial on of the high rate solution into a solution
containing appropriate volume of 97:3 v/v mixture of e and DMSO and riate
volume of an aqueous mixture of water, isopropyl l, crop oil concentrate (78:20:2,
v/v/v) containing 0.02% Triton X-155.
Formulated compounds were applied using a DeVilbiss® compressed air sprayer
at 2—4 pounds per square inche (psi). Following treatment, pots were ed to the
greenhouse for the duration of the experiment. All pots were sub-irrigated as need to
provide optimum growing conditions. All pots were fertilized one time per week by
subirrigating with Peters Peat-Lite Special® fertilizer (2020).

Example B. Evaluation of Preemergent Herbicidal Activity
Pre-Emergent Test 1: Seeds of test species were d into round plastic pots
(5-inch diameter) containing sandy loam soil. After planting, all pots were sub-irrigated 16 h
prior to compound application.
Compounds were dissolved in a 97:3 v/v mixture of acetone and DMSO and
diluted to the appropriate concentration in a final application solution containing water,
acetone, isopropanol, DMSO and Agri-dex (crop oil concentrate) in a 59:23:15:l.0: l .5 v/v
ratio and 0.02% w/v (weight/volume) of Triton X-lSS to obtain the spray solution
containing the t application rate. Additional application rates were obtained by serial
dilution of the high rate solution with the above application solution.
Formulated nd (2.7 mL) was pipetted evenly over the soil e
ed by incorporation with water (15 mL). Following treatment, pots were returned to
the greenhouse for the duration of the experiment. The greenhouse was programmed for an
imate 15 h photoperiod which was ined at about 23—290C during the day and
22—280C during the night. Nutrients and water were added on a regular basis through
surface tion and supplemental lighting was provided with overhead metal halide 1000-
Watt lamps as necessary.
Herbicidal effect ratings were obtained 14 days after treatment. All evaluations
were made relative to appropriate controls on a scale of 0 to 100 where 0 represents no
herbicidal effect and 100 represents plant death or lack of emergence from the soil and is
presented as ted in Table A. Some of the compounds tested, application rates
employed, plant species tested, and results are given in Table 4.

Example C. Evaluation of Postemergent Herbicidal Activity
Post-Emergent Test 11: Seeds or s of the desired test plant species were
planted in Sun Gro Metro-Mix® 360 ng e, which typically has a pH of 6.0 to 6.8
and an c matter content of about 30 percent, in plastic pots with a surface area of 64
square centimeters. When required to ensure good germination and healthy plants, a
ide treatment and/or other chemical or physical treatment was applied. The plants
were grown for 7—21 d in a greenhouse with an approximate 15 h eriod which was
maintained at about 23—29 c’C during the day and 22—28 c’C during the night. Nutrients and
water were added on a regular basis and supplemental lighting was provided with overhead
metal halide lOOO-Watt lamps as necessary. The plants were employed for testing when
they reached the first or second true leaf stage.
] A weighed amount, determined by the highest rate to be tested, of each test
compound was placed in a 25 mL glass vial and was ved in 4 mL of a 97:3 v/v mixture
of e and DMSO to obtain concentrated stock solutions. If the test compound did not
dissolve readily, the e was warmed and/or sonicated. The concentrated stock
solutions obtained were diluted with 20 mL of an aqueous mixture containing acetone,
water, isopropyl alcohol, DMSO, Atplus 411F crop oil concentrate, and Triton® X-155
surfactant in a 48.5 :39: 10: 1 .5 : 1 .0:0.02 v/v ratio to obtain spray solutions containing the
highest application rates. Additional application rates were obtained by serial dilution of 12
mL of the high rate solution into a solution containing 2 mL of 97:3 v/v mixture of acetone
and DMSO and 10 mL of an aqueous mixture containing acetone, water, isopropyl alcohol,
DMSO, Atplus 411F crop oil concentrate, and Triton X-155 surfactant in a
48.5:39:10:1.5:1.0:0.02 v/v ratio to obtain 1/2X, 1/4X, 1/8X and 1/16X rates ofthe high rate.
Compound requirements are based upon a 12 mL application volume at a rate of 187 liters
per hectare (L/ha). Formulated compounds were applied to the plant material with an
overhead Mandel track sprayer ed with 8002B nozzles calibrated to deliver 187 L/ha
over an application area of 0.503 square meters at a spray height of 18 inches (43 cm) above
the average plant canopy height. Control plants were sprayed in the same manner with the
solvent blank.
[00366] The treated plants and control plants were placed in a greenhouse as described
above and watered by subirrigation to prevent wash-off of the test compounds. After 14 d,
the condition of the test plants as compared with that of the untreated plants was determined
visu nd scored on a scale of 0 to 100 percent where 0 corresponds to no injury and 100
corresponds to complete kill and is ted as indicated in Table A. Some of the

Example D. Evaluation of Postemergent Herbicidal Activity in Wheat and Barley
Post-Emergent Test 111. Seeds of the desired test plant species were planted in Sun
Gro MetroMix® 306 ng mixture, which typically has a pH of 6.0 to 6.8 and an organic
matter content of about 30 percent, in plastic pots with a surface area of 103.2 square
centimeters (cmz). When required to ensure good germination and healthy plants, a fimgicide
treatment and/or other chemical or physical treatment was applied. The plants were grown
for 7-36 d in a greenhouse with an approximate 14 h photoperiod which was ined at
about 18 CC during the day and 17 CC during the night. Nutrients and water were added on a
regular basis and supplemental lighting was provided with overhead metal halide lOOO-Watt
lamps as necessary. The plants were employed for testing when they reached the second or
third true leaf stage.
A weighed amount, determined by the highest rate to be , of each test
compound was placed in a 25 mL glass vial and was dissolved in 4 mL of a 97:3 v/v e
of e and DMSO to obtain concentrated stock solutions. If the test compound did not
dissolve readily, the mixture was warmed and/or sonicated. The concentrated stock solutions
ed were diluted with 20 mL of an aqueous e ning acetone, water, isopropyl
alcohol, DMSO, Agri-Dex crop oil concentrate, and X-77 surfactant in a
48:39: 10: l .5 : l .5 :0.02 v/v ratio to obtain spray solutions containing the highest application
rates. Additional application rates were obtained by serial dilution of 12 mL of the high rate
solution into a solution ning 2 mL of 97:3 v/v mixture of e and DMSO and 10
mL of an aqueous mixture containing acetone, water, isopropyl alcohol, DMSO, Agri-Dex
crop oil trate, and X-77 surfactant in a 48:39: 10: l .5:l.5:0.02 v/v ratio to obtain l/2X,
l/4X, 1/8X and l/16X rates of the high rate. Compound requirements are based upon a 12
mL application volume at a rate of 187 liters per hectare (L/ha). Formulated nds
were applied to the plant material with an overhead Mandel track sprayer equipped with
8002E nozzles ated to deliver 187 L/ha over an application area of 0.503 square meters
at a spray height of 18 inches (43 cm) above the average plant canopy height. Control plants
were sprayed in the same manner with the solvent blank.
The treated plants and l plants were placed in a ouse as described
above and watered by subirrigation to prevent wash-off of the test nds. After 21 d,
the condition of the test plants as compared with that of the untreated plants was determined
visually and scored on a scale of 0 to 100 percent where 0 corresponds to no injury and 100
corresnds to complete kill and is presented as indicated in Table A.

By ng the well-accepted probit analysis as described by J. Berkson in
Journal oft/w American Statistical Society, 48, 565 (1953) and by D. Finney in “Probit
Analysis” dge University Press (1952), herbicidal injury of a specific compound at
various rates can be used to ate GRZO, GRSO, GRgo and GR90 values, which are defined
as growth ion factors that correspond to the ive dose of herbicide ed to
provide plant growth reduction (GR) of 20 percent, 50 percent, 80 percent and 90 percent,
respectively. Probit analysis was applied to data collected from multiple dose rates of
individual compounds utilizing the procedures explained in the following examples. The
data for some of the dose rates and analysis of all of the dose rates are captured in the
following tables.
Some of the compounds tested, application rates employed, plant species tested,
and results are given in Tables 7 through ll.

e E. Evaluation of Preemergent Herbicidal Activity
Pre-Emergent Test 111. Seeds of test species were planted into square plastic pots
(10 cm wide) containing sandy loam soil. After planting, all pots were sub-irrigated 16 h
prior to compound application.
[00373] A weighed amount, determined by the highest rate to be tested, of each test
compound was placed in a 25 mL glass vial and was ved in 4 mL of a 97:3 v/v mixture
of acetone and DMSO to obtain concentrated stock solutions. If the test compound did not
dissolve readily, the mixture was warmed and/or sonicated. The concentrated stock solutions
obtained were d with 20 mL of an aqueous e containing water and 0.02% w/v
(weight/volume) of Triton X-l55 to obtain spray solutions containing the highest application
rates. Additional application rates were obtained by serial dilution of 12 mL of the high rate
solution into a solution containing 2 mL of 97:3 v/v mixture of acetone and DMSO and 10
mL of an s mixture containing water and 0.02% w/v (weight/volume) of Triton X-l55
to obtain l/2X, l/4X, 1/8X and l/16X rates of the high rate. Compound requirements are
based upon a 12 mL application volume at a rate of 187 liters per hectare (L/ha). Formulated
compounds were applied to the soil surface with an overhead Mandel track sprayer equipped
with 8002E nozzles ated to deliver 187 L/ha over an application area of 0.503 square
meters. Control pots were sprayed in the same manner with the solvent blank.
The treated pots and control pots were placed in a greenhouse as described above
and watered through surface irrigation. After 21 d, the condition of the test pots as compared
with that of the untreated pots was ined visually and scored on a scale of 0 to 100
percent where 0 ponds to no herbicidal effect and 100 corresponds to plant death or
lack ofiiergence from the soil and is presented as indicated in Table A.

By applying the well-accepted probit analysis as described by J. Berkson in
l oft/w American Statistical Society, 48, 565 (1953) and by D. Finney in “Probit
is” Cambridge University Press (1952), herbicidal injury of a specific compound at
various rates can be used to calculate GRZO, GRSO, GRgo and GR90 , which are defined
as growth reduction factors that correspond to the effective dose of herbicide required to
provide plant growth reduction (GR) of 20 percent, 50 percent, 80 percent and 90 percent,
respectively. Probit analysis was applied to data collected from multiple dose rates of
individual compounds utilizing the procedures ned in the following examples. The data
for some of the dose rates and analysis of all of the dose rates are captured in the following
tables.
Some of the compounds tested, ation rates employed, plant species tested,
and results are given in Table 12.

other chemical or physical treatment was d. The plants were grown for 10—17 d in a
greenhouse with an approximate 14-h photoperiod which was maintained at about 29 CC
during the day and 26 CC during the night. Nutrients and water were added on a regular basis
and supplemental lighting was provided with overhead metal halide att lamps as
ary. The plants were employed for testing when they reached the second or third true
leaf stage.
A weighed amount, determined by the highest rate to be tested, of each test
compound was placed in 25 mL glass vials and dissolved in a volume of 97:3 v/v acetone—
DMSO to obtain 12X stock solutions. If the test compound did not dissolve readily, the
mixture was warmed and/or ted. The concentrated stock solutions were added to the
spray solutions so that the final acetone and DMSO concentrations were 16.2% and 0.5%,
respectively. Spray solutions were diluted to the riate final concentrations with the
addition of 10 mL of an aqueous mixture of 1.5% (v/v) ex crop oil concentrate. The
final spray solutions contained 1.25% (v/v) Agri-dex crop oil concentrate. Compound
requirements are based upon a 12 mL application volume at a rate of 187 L/ha. Formulated
compounds were applied to the plant material with an overhead Mandel track sprayer
equipped with 8002E nozzles calibrated to deliver 187 L/ha over an application area of 0.503
square meters (m2) at a spray height of 18 inches (43 cm) above average plant canopy height.
Control plants were d in the same manner with the solvent blank.
The treated plants and control plants were placed in a greenhouse as described
above and watered by sub-irrigation to prevent wash-off of the test compounds. After 20—22
d, the condition of the test plants, compared with that of the untreated plants, was determined
visually and scored on a scale of 0 to 100 percent where 0 corresponds to no injury and 100
corresponds to complete kill and is presented as indicated in Table A.
By applying the well-accepted probit is as described by J. Berkson in
Journal oft/w American Statistical Society, 48, 565 (1953) and by D. Finney in “Probit
Analysis” Cambridge University Press (1952), herbicidal injury of a c compound at
various rates can be used to calculate GRZO, GRSO, GRgo and GR90 values, which are defined
as growth reduction factors that correspond to the effective dose of herbicide required to
provide plant growth reduction (GR) of 20 percent, 50 percent, 80 percent and 90 percent,
respectively. Probit analysis was applied to data collected from multiple dose rates of
indivibl compounds ing the procedures explained in the ing examples. The
