Abstract:Piperidine-4-carboxylic acid and ethyl carbonochloridate were used as the starting materials for preparation of (2,4-difluorophenyl)(piperidin-4-yl)methanone hydrochloride(4) via amidation,Friedel-crafts acylation and hydration. The staring materials were easily available and the process afforded a reasonable overall yield of 62.4%. The structures of the intermediates and the target compound were identified with 1H NMR.
Key words:Risperidone;piperidine-4-carboxylic acid;Friedel-crafts acylation;process improvement
