Abstract: The structural analysis of the title compound, C14H14N2O4S, particularly the presence of an acetyl group at the exocyclic N atom and the C(H)-C(O2CMe)-N acetoxy group in the thiazole ring, may indicate that one of the starting materials, i.e. 2-(4-methoxyanilino)-1,3-thiazol-4(5H)-one, exists in the reaction mixture, at least partially, as a tautomer with an exocyclic amine N atom and an enol group. The acetoxy and acetyl groups deviate from the thiazole plane by 69.17 (6) and 7.25 (19)°, respectively. The thiazole and benzene rings form a dihedral angle of 73.50 (4)°. In the crystal, centrosymmetrically related molecules are connected into dimeric aggregates via C-HO interactions.
