Definitions
- the invention relates to a process for the preparation of compounds of the formula I.
- A stands for an alkyl group with 1 to 6 carbon atoms.
- Drugs that contain the heterocycle system of compounds of formula I are described for example in DE-198 190 23 AI. These compounds and their salts are well tolerated and have very valuable pharmacological properties. In particular, they show a specific inhibition of cGMP phosphodiesterase (PDE V).
- PDE V cGMP phosphodiesterase
- the compounds are therefore suitable for the treatment of diseases of the cardiovascular system, in particular heart failure and for the treatment and / or therapy of erectile dysfunction (ectile dysfunction).
- erectile dysfunction ectile dysfunction
- suitable starting compounds can be provided in sufficient quantities. Because of the strict requirements regarding the purity of the drugs, they should be obtained with great purity. The reaction should also proceed in high yield to keep costs down and avoid waste disposal problems.
- the object of the invention is to provide a process for the preparation of compounds of the formula I which is simple to carry out and which provides the compound of the formula I in good yields and in high purity.
- R ⁇ stands for a linear or branched alkyl group with 1 to 6 carbon atoms, especially methyl, and a nitrile of the formula III
- R 1 has the meaning given above, are reacted in a solvent in solution or suspension in the presence of an acid.
- the radical R of the carboxylic acid ester of the formula II is preferably methyl, ethyl or propyl, further preferably isopropyl, butyl, isobutyl, sec-butyl or tert-butyl, but also n-pentyl, neopentyl. Isopentyl or hexyl used.
- the alkylene radical is preferably, for example, methyl, ethyl, propyl, isopropyl, butyl, isobutyl, sec-butyl, pentyl, 1-, 2- or 3-methylbutyl, 1,1-, 1,2- or 2,2-dimethylpropyl , 1-ethylpropyl, hexyl, 1-, 2-, 3- or 4-methylpentyl, 1,1-, 1,2-, 1,3-, 2,2-, 2,3- or 3,3-dimethylbutyl , 1- or 2-ethylbutyl, 1-ethyl-1-methylpropyl, 1-ethyl-3-methylpropyl, 1,1,2- or 1,2,2-trimethylpropyl, linear or branched heptyl, octyl, nonyl or decyl , Furthermore, R 1 can be but-2-en-yl or hex-3-en-yl.
- Cyclopentylmethylene, cyclohexylmethylene, cyclohexylethylene, cyclohexylpropylene or cyclohexylbutylene can be used as cycloalkyl or cycloalkylalkylene radicals having 5 to 12 carbon atoms.
- the cycloalkyl radicals preferably comprise 5 to 7 carbon atoms. Examples are cyclopentyl, cyclohexyl or cycloheptyl groups.
- R 1 can be a phenyl or a phenylmethyl radical.
- radicals mentioned are each simply substituted by -COOH, -COOA, -CONH 2 , -CONHA, - CON (A) 2 or -CN.
- A stands for alkyl with 1 to 6 carbon atoms. Examples of suitable groups are methyl, ethyl or propyl, and isopropyl, butyl, isobutyl, sec-butyl or tert-butyl as well as n-pentyl, neopentyl, isopentyl or hexyl.
- the compounds of the formula I are obtained as salts. These generally precipitate out of the reaction solution as a crystalline precipitate and can be obtained in sufficient purity by simple filtration.
- the synthesis of the compound of formula I is generally carried out in such a way that the carboxylic acid ester of formula II and the nitrile of formula III are placed in a suitable solvent and then the acid is added, for example by introducing it into the solution as a gas ,
- the yield of the reaction and the purity of the reaction product of the formula I can, however, be significantly increased and the reaction time considerably shortened if an excess of acid is first dissolved in the solvent, preferably the solvent is saturated with the acid, and then the 2-aminobenzothiophene 3-carboxylic acid esters of the formula II and the nitrile of the formula III are added.
- An excess of acid is understood to mean such a high amount of acid that with quantitative conversion of the compounds of the formula I and II and subsequent precipitation as a salt, unbound acid still remains in the solution. This amount of acid should already be present in the reaction mixture at the beginning of the reaction.
- the reaction can be carried out in such a way that first a, preferably saturated, solution of the acid in the solvent is prepared and, separately therefrom, a solution which contains the compounds of the formula I and the formula II.
- the two solutions can then either be poured into a reaction vessel for reaction at the same time, or the acid solution is introduced and the solution of the compounds of the formula I and the formula II is added.
- the acid solution should be added as quickly as possible to dissolve the compounds of the formula I and the formula II.
- the solvent is selected from the group formed by ethers, alcohols, esters, water, formamides, amines, carboxylic acids, chlorinated hydrocarbons and mixtures thereof.
- a particularly suitable solvent is dioxane.
- Suitable ethers are, for example, diethyl ether, diisopropyl ether. Tetrahydrofuran or dioxane.
- Suitable alcohols are, for example, methanol, ethanol, isopropanol. n-propanol, n-butanol or tert-butanol.
- Glycol ethers such as ethylene glycol monomethyl or monoethyl ether (methyl glycol or ethyl glycol), diethylene glycol dimethyl ether (diglyme) are also suitable.
- Suitable amides are, for example, acetamide, dimethylacetamide, N-methylpyrrolidone or dimethylformamide.
- a suitable carboxylic acid is, for example, glacial acetic acid.
- ethyl acetate can be used as the ester.
- Suitable chlorinated hydrocarbons are, for example, trichlorethylene, 1,2-dichloroethane, carbon tetrachloride, chloroform or dichloromethane. Mixtures of the solvents mentioned can also be used.
- the acids are suitably selected from the group that is formed by
- Bronsted acids and Lewis acids especially hydrochloric acid, hydrobromic acid, sulfuric acid, phosphoric acid, polyphosphoric acid, methanesulfonic acid, Trifluoromethanesulfonic acid, trifluoroacetic acid, aluminum trichloride and boron trifluoride.
- Gaseous acids, in particular hydrogen chloride, are particularly suitable.
- the reaction is suitably carried out at a temperature of -10 ° C to 100 ° C, preferably 0 ° C to 60 ° C, especially 10 ° C to 50 ° C.
- the compounds of the formula I represent a valuable starting material for further syntheses.
- a further activation of the compound of the formula I can be achieved if, in a further step, the compound of the formula I with a chlorinating agent into a compound of the formula IV
- the chlorine can easily be substituted by appropriate nucleophiles.
- the chlorinating agent is suitably selected from the group formed by SOCl 2 , POCl 3 , PCI 5 , C1COCOC1.
- the compounds of the formula II and III are either known or can be prepared by a person skilled in the art by known synthetic routes.
- An exemplary synthesis of the compounds of the formulas II and III is described below on the basis of particularly preferred compounds.
- the reactions can be carried out analogously for other radicals R 1 and R 2 .
- trans-4-cyanocyclohexanecarboxylic acid methyl ester starts from trans-cyclohexane-1,4-dicarboxylic acid methyl ester £, which is first saponified with KOH to form monomethyl ester 9. This is first converted into the acid chloride with thionyl chloride and then into the acid amide IQ with ammonia. The desired nitrile 11 is finally obtained from the acid amide IQ. H 3 COOC, HOOC, OH 1. SOCl 2
- compounds 2 and 11 are cyclized to give imidone 12.
- compound L2 By reaction with thionyl chloride, compound L2 can be obtained whose chlorine group can be substituted nucleophilically and is thus available as a starting compound for the synthesis of a large number of pharmacologically active substances.
