摘要:
The present invention relates to a novel and improved process for the preparation of N-[4-[2-(dimethylamino)ethoxy]benzyl]-3,4-dimethoxybenzamide-known as Itopride, via a novel intermediate N-(4~hydroxybenzyl)-3,4-dimethoxybenzamide.
摘要:
Nateglinide is prepared by an improved process comprising reaction of trans-4-isopropyl cyclohexane carbonyl chloride with N,O-bis- trimethylsilyl protected D-phenyl alanine to give after aqueous workup, crude nateglinide which is converted to Nateglinide form- H using a mixture of cyclohexane / ethyl acetate. trans-4-isopropyl cyclohexane carbonyl chloride is prepared from trans-4- isopropyl cyclohexane carboxylic acid using oxalyl chloride.

摘要:
The present invention relates to an improved and one-pot process for the preparation of 1-Aryl 2-aminomethyl cyclopropane carboxyamide (z) derivatives, their isomers of formula (I) or its pharmaceutically acceptable salt thereof wherein R 1 and R 2 are represents independently selected from the group consisting of hydrogen, lower alkyl, lower aryl, and lower-alkylaryl, which aryl or alkylaryl group is optionally substituted by a halogen atom.
