In the title compound, C17H15NO2S, the seven-membered thiazepine ring adopts a distorted twist-boat conformation. The dihedral angle between the mean planes of the benzothiazepin ring system and the attached benzene ring is 47.7 (1)°. In the crystal, pairs of N-HO hydrogen bonds link inversion-related molecules into dimers, generating R22(8) ring motifs. These dimers are further connected into a chain along the a axis by C-HO hydrogen bonds, resulting in R22(14) ring motifs. The crystal packing also features C-H interactions.
