Abstract

A facile one-pot two-step process for the synthesis of ethyl 2-imino-4-methyl-2,3-dihydrothiazole-5-carboxylates via the cyclocondensation of ethyl 2-thiocyanatoacetoacetate with a variety of hydrazine and hydrazide derivatives has been developed. Ethyl 2-thiocyanatoacetoacetate itself has been synthesized as intermediate from the reaction of ethyl 2-chloroacetoacetate with potassium thiocyanate (KSCN). The molecular structures of these newly synthesized compounds were elucidated on the basis of elemental analysis and spectral data.
