In the title compound, C15H16N4O3S, the six-membered heterocycle of the benzo-thia-zine fragment exhibits a screw boat conformation. The dihedral angle between the planes through the triazole ring and the benzene ring fused to the 1,4-thia-zine ring is 62.98 (11)°. The mean plane formed by the atoms belonging to the acetate group is nearly perpendicular to the triazole ring [dihedral angle = 74.65 (12)°]. In the crystal, mol-ecules are linked by pairs of C-H⋯O inter-actions, forming dimeric aggregates.
