ABSTRACT An efficient route for the synthesis of (E)-2-(2-(2-nitrobenzylidene)-hydrazinyl)-4-phenylthiazol-3-ium bromide, (E)-2-(2(substituted benzylidene)hydrazinyl)-4-phenylthiazoles and (E)-4-(4-bromophenyl)-2-(cycloalkylidenehydrazono)-3-phenyl-2,3-dihydrothiazoles by reaction of 1-aryl-2-bromoethanones with 2-(1-substituted methylidene)hydrazinecarbothioamides and cycloalkylidene-N-phenyl-hyd
