A variety of 2-halo-5-thiazolecarboxylates was prepared from substituted-3-aminoacrylates and 3-ketoesters.Selective reduction of 2-chloro-5-thiazolecarboxylates 4a, 4i and 4j with sodium borohydride in ethanol provided the corresponding 2-halo-5-thiazolemethanols 27 - 29.Nucleophilic displacement on methyl methanesulfonate (32c) occured selectivity at the 5-substituent to provide 2-chloro-4-(trifluoromethyl)-5-(heteroatom-substituted methyl)thiazoles 32d-f.
