In the title compound, C17H18N2S, the thiazepine ring adopts a boat conformation and the dihedral angle between the benzene rings is 75.92 (5)°, resulting in a butterfly-like conformation. In the crystal, molecules are connected via weak Caromatic—HN contacts involving the imine N atom as acceptor and through a quite short C—Hπ interaction. The resulting molecular chains propagate along the c-axis direction.
