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.
