Process for the preparation of thiazolecarboxylic acid chlorides

Disclosed herein is a process for the preparation of a thiazolecarboxylic acid chloride represented by the following general formula (II): STR1 wherein R1 represents a hydrogen or halogen atom, a lower alkyl group, a lower alkoxy group, or a lower alkyl group substituted by a halogen atom or lower alkoxy group, and R2 represents a hydrogen atom, a lower alkyl group, or a lower alkyl group substituted by a halogen atom or lower alkoxy group, which comprises reacting a thiazolecarboxylic acid represented by the following general formula (I): STR2 wherein R1 and R2 have the same meanings as defined with respect to formula (II), with phosgene or trichloromethyl chloroformate in the presence or absence of a catalyst.
