Butyl 3-oxo-2,3-dihydrobenzo[d][1,2]thiazole-2-carboxylate

Abstract

The title compound, C12H13NO3S, was synthesised by the reaction of benzo[d]isothiazol-3(2H)-one with butyl alcohol in toluene. The benzoisothiazolone ring system is almost planar with a mean deviation of 0.041 (1) Å. In the crystal, molecules are linked by weak intermolecular C—H...O hydrogen bonds.
