ABSTRACT:
The invention relates to processes for the preparation of clopidogrel and salts thereof. The inventors have developed a process for preparing racemic clopidogrel by racemizing R(−) clopidogrel. The process includes the step of reacting R(−) clopidogrel with a powered anhydrous base in one or more solvents.
