Abstract

N - Alkyl - alkyl - piperidine - monocarboxylic acid amides and N-alkyl-alkyl-pyrrolidine monocarboxylic acid amides of the formul\mg <FORM:0799779/IV (b)/1> respectively, wherein R1 is an alkyl group, R2 and R3 are each an alkyl group or one is alkyl and the other is hydrogen, and Ar is an unsubstituted benzene ring or an alkyl, alkoxy, hydroxy and/or chloro-substituted benzene ring, are prepared by reacting an aniline- or appropriately substituted aniline-magnesium halide with an alkyl-pyrrole or -pyrrolidine monocarboxylic acid ester or an alkyl-pyridine or -piperidine monocarboxylic acid ester, which may or may not be N-alkylated, hydrolysing the reaction product with an acid and, when necessary, hydrogenating the heterocyclic ring and alkylating the nuclear nitrogen atom. Preferred aniline magnesium halides are those in which Ar is substituted with an alkyl group or chlorine in the 2-position, with or without a hydroxy, alkyl or alkoxy group in the 4-position and with or without chlorine or an alkyl or alkoxy group in the 6-position. The examples describe the preparation of N-methyl-4-methyl-piperidine - a - monocarboxylic acid - 2 : 6 - dimethyl - anilide, N - ethyl - 6 - methyl - piperidine - b - monocarboxylic acid - 2 - ethyl anilide, N - n - propyl - 4 - methyl-pyrrolidine - a - monocarboxylic acid-2 : 6-dimethyl anilide and N-methyl - 4 : 6 - dimethyl - piperidine - a - monocarboxylic acid - 2 - methyl - 6 - chloro - anilide. Specifications 799,778 and 799,780 are referred to.
