Abstract

In the title compound, C10H10N2O2S, the thiazine ring approximates to an envelope form with the S atom in the flap position. The amide group attached to the acetate group is almost perpendicular to the mean plane of the thiazine ring [dihedral angle = 88.83 (8)°]. In the crystal, inversion dimers linked by pairs of N—H⋯O hydrogen bonds occur. Further N—H⋯O and C—H⋯O hydrogen bonds link the dimers into a three-dimensional network.
