标 题 :Process for the synthesis of zolpidem
发明人：KUMAR YATENDRA; PRASAD MOHAN; NATH ASOK
摘要:The present invention relates to processes for the preparation of zolpidem of Formula V as shown in the accompanying drawings or pharmaceutically acceptable salts thereof from N,N-dimethyl-3-(4-methyl)benzoyl propionamide of Formula II. The process includes (a) reacting N,N-dimethyl-3-(4-methyl)benzoyl propionamide of Formula II with bromine to get the bromo amide of Formula III; (b) condensing the bromo amide of Formula III with 2-amino-5-methylpyridine of Formula IV to get the zolpidem base of Formula V; and (c) converting zolpidem base of Formula V to its hemitartarate salt of Formula VII.
