2-(Benzenesulfonyl)-4-tosyl-1,3-thiazole was synthesized starting from the available 2,2-dichloro-1-tosylethenyl isothiocyanate. The product is a pronounced electrophilic substrate feasible for investigation of the order of nucleophilic substitution at the C(2), C(4), and C(5) centers of the thiazole ring. Different nucleophilic agent first attack the C(2) atom. After that S-nucleophiles react with C(5), while O- and N-nucleophiles, with C(4).
