Abstract

A process for obtaining hydrogenated amides of N-alkyl-alkyl-piperidin monocarboxylic acid and N-alkyl-alkyl-pyrrolidin monocarboxylic acid, according to the formulas ** (See formula) ** wherein R1 designates an alkyl group, R2 and R3, either an alkyl group each or an alkyl group and the other a hydrogen atom, and in which Ar consists of a substituted benzene nucleus in which the substitution preferably consists of alkyl or alkoxy groups, characterized in that an alkyl magnesium halide of the formula: ** (See formula) ** wherein X denotes the halide and R4, R5 and R6 are substituents, such as a hydrogen atom, an alkyl group, a chlorine atom or an alkoxy group, is reacted with an ester, hydrogenated or not, of N-acid -alkyl pyrrolidine monocarboxylic or N-alkyl piperidine monocarboxylic which is or is not alkylated to the ring nitrogen, the mixture being maintained under reflux under continuous stirring, then cooling. The product of the reaction is then hydrolysed with an acid, whereby the impurities formed of magnesium are dissolved and hydrolyzed. The pH is adjusted to a value below 7, the aqueous base is separated and the excess that has not reacted with the ester is extracted with an aromatic solvent. The product formed is obtained by extracting it with a solvent liquid of the amide, after adding an excess of ammonia to the aqueous solution. The isoamyl alcohol solution is evaporated to dryness, the product is then dissolved in dilute hydrochloride, treated with activated carbon and finally precipitated with sodium hydroxide. Only the catalytic hydrogenation of the heterocyclic ring is carried out, and the alkylation of the ring nitrogen when this is the case. (Machine-translation by Google Translate, not legally binding)
