Abstract

The synthesis of methyl 2-acetylamino-5-(1,3-dithian-2-yl)thiazole-4-carboxylate (4) by formylation of a 4-substituted thiazole and then reaction with 1,3-propanedithiol are described. The utility of different ortho-directing groups (ODGs) for the lithiation of the thiazole 4-position has been studied
