    摘要: The present invention provides a process for the preparation of clopidogrel and its pharmaceutically acceptable salts thereof comprises the resolving racemic methyl alpha-5-(4,5,6,7-tetrahydro[3,2-c]thienopyridyl)(2-chlorophenyl)-acetate by the salt formation of methyl alpha-5-(4,5,6,7-tetrahydro[3,2-c]thienopyridyl)(2-chlorophenyl)-acetate with excess levorotatory camphor-10-sulfonic acid to get a maximum yield of camphor sulphonate salt of methyl S-(+)-alpha-5-(4,5,6,7-tetrahydro[3,2-e]thienopyridyl)(2-chlorophenyl)-acetate and transforming the camphor sulphonate salt to clopidogrel or its pharmaceutically acceptable salts thereof.

    摘要: The present invention relates to a process for the preparation of Form 1 of (+)-(S)-∞-(2-Chlorophenyl)-6,7-dihydrothieno[3,2-c]pyridine-5(4H)-acetic acid methyl ester hydrogen sulphate commonly known as clopidogrel bisulphate. The present invention further relates to a process for reducing the residual amount of methyl isobutyl ketone and controlling the amount of mesityl oxide in clopidogrel hydrogen sulphate Form 1 by washing with ethyl acetate. Formula (I).
