摘要： 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.
