In the title compound, C16H13NOS, the 1,4-thiazine ring displays a screw-boat conformation. The conformation about the ethene bond [1.344 (2) Å] isZ. The plane of the fused benzene ring makes a dihedral angle of 58.95 (9)° with the pendent phenyl ring, indicating a twisted conformation in the molecule. In the crystal, molecules are linked by pairs of C—H...O hydrogen bonds, forming inversion dimers.
