The present invention relates to a method of converting an alcohol into a corresponding halide. This method comprises reacting the alcohol with an optionally substituted aromatic carboxylic acid halide in presence of an N-substituted formamide to replace a hydroxyl group of the alcohol by a halogen atom. The present invention also relates to a method of converting an alcohol into a corresponding substitution product. The second method comprises: (a) performing the method of the invention of converting an alcohol into the corresponding halide; and (b) reacting the corresponding halide with a nucleophile to convert the halide into the nucleophilic substitution product.

Clopidogrel is a prodrug anticoagulant with activemetabolites that irreversibly inhibit the platelet surface GPCR P2Y12 and thus inhibit platelet activation. However, gaining an understanding of patient response has been limited due to imprecise understanding of metabolite activity and stereochemistry, and a lack of acceptable analytes for quantifying in vivo metabolite formation.

Multicomponent reactions (MCRs) are not only a powerful tool for drug discovery, they also represent an excellent methodology for synthesis rationalization. Here we wish to illustrate the potential of MCRs in the production of generic drugs by synthesizing, in racemic form, the antiplatelet agent clopidogrel and the non-steroidal antiandrogen bicalutamide, using Ugi, Petasis and Passerini reactions.
