Abstract: In the title compound, C₁₆H₁₅N₃O₃S, the dihedral angle between the aromatic rings is 8.18 (11)° and the C=N-N=C torsion angle is 178.59 (14)°. The conformation of the thiazine ring is an envelope, with the S atom displaced by 0.8157 (18) Å from the mean plane of the other five atoms (r.m.s. deviation = 0.045 Å). An intramolecular O-HN hydrogen bond closes an S(6) ring. In the crystal, weak C-HO interactions link the molecules, with all three O atoms acting as acceptors.
