Abstract

There are two mol­ecules, A and B, in the asymmetric unit of the title compound, C14H16N2O4S, which is the first example reported in this family of compounds in which the Nsp 3 atom of the thia­diazine ring is methyl­ated. The thia­diazine rings adopt shallow envelope conformations, with the S atoms displaced by 0.319 (12) and 0.182 (12) Å from the mean planes of the other ring atoms in mol­ecules A and B, respectively. The dihedral angles between the thia­diazine mean planes (excluding S) and the attached benzene rings are 86.8 (3) and 86.7 (3)° for mol­ecules A and B, respectively.
