In the title compound, C16H13N3OS, the thiomorpholine ring exists in a screw boat conformation. The angle between the benzimidazole ring system and the benzene ring fused to the thiazine ring is 67.22 (6)°. In the crystal, molecules form infinite chains along the a axis via intermolecular N—H⋯N interactions. C—H⋯π interactions also contribute to the stability of the crystal structure.
