The mean plane of the cyclo-hexane ring is almost normal to the benzene ring and the mean plane of the 1,2,4-thia-diazinane ring, making dihedral angles of 70.4 (2) and 71.43 (19)°, respectively. Furthermore, the dihedral angle between the benzene ring and the mean plane of the 1,2,4-thia-diazinane ring is 4.91 (18)°. The mol-ecular structure is stabilized by an intra-molecular C-H⋯O hydrogen bond, which encloses an S(6) ring motif. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds into chains along [10-1], forming a C(6) graph-set motif. These chains are inter-cActa crystallographica.
