A simple one-pot synthesis of 3-alkyl-4-methyl-2-phenylimino-2,3-dihydrothiazoles from the reaction of phenylisothiocyanate, primary alkylamines and 2-chloro-1,3-dicarbonyl compounds under solvent-free conditions is described.

A one-potthree-component approach for the synthesis of thiazol-2-imines has been described by the reaction of amine, phenyl isothiocyanate and β-nitroacrylate in [Hbim]BF4 ionicliquid. The method is applicable for aromatic, benzylic, aliphatic and cyclic amines. Reusable reaction media, regioselectivity, mild reaction condition, catalyst free and high yield of products are the salient features of
