In the title compound, C19H18ClNOS, the thiazin-3-one ring adopts a slightly distorted screw-boat conformation. An intramolecular C—H...S hydrogen bond encloses an S(6) ring and affects the overall conformation of the molecule. The dihedral angle between the two phenyl rings is 52.3 (2)°. In the crystal, weak C—H...O intermolecular interactions stabilize the crystal packing.
