Abstract: The reactions of 2-bromomethyl-4-bromophenyl isothiocyanate (pre­pared by radical bromination of 2-methyl-4-bromophenyl isothiocyanate with 7V-bromosuccinimide) with amines and sodium phenolate proceed on the NCS group under formation of unstable addition products which, at the reaction conditions, cyclize to the respective 4H-benzo[d]-l,3-thiazines. The structures of the synthesized compounds were proved by spectral methods.
