The preparation of 4- and 5-acyl- and aroyl-2-substituted aminothiazoles is described. The condensation of thioureas with acyl halides leading to 4,5-disubstituted-2-aminothiazoles and 7-(4H)benzothiazolones is discussed. A discussion of the isolation of various intermediates and the mechanistic pathway is also included. A number of 2-anilino or 2-benzyl-4- or 5-aroylthiazoles possessed moderate oral
produce pyridyl aminothiazole derivatives. Also the pyridyl aminothiazole derivatives were obtained by the reaction of 2-aminopyridine with benzoyl isothiocyanates and phenacyl bromide in the presence of triethylamine.
