【 摘 要 】

In the title compound, C17H13NO3S, the thiazine ring displays a screw-boat conformation. The dihedral angle between the terminal benzene ring and the mean plane of the 1,4-benzothiazine fused-ring system is 51.52 (6)°. In the crystal, inversion dimers linked by pairs of O—H...Ot (t = thiazine) hydrogen bonds generate R22(14) loops. The dimers are linked by pairwise C—H...O hydrogen bonds, resulting in [010] chains.
