In the title mol-ecule, C(18)H(17)N(5)O(3)S(2), the heterocyclic thia-zine ring adopts a twist boat conformation, with the S and N atoms displaced by 0.480 (7) and 0.205 (8) Å, respectively, on opposite sides of the mean plane formed by the remaining ring atoms. The pyrazole and benzene rings are tilted at an angle of 10.9 (2)° with respect to one another. The crystal structure is stabilized by inter-molecular N-H⋯O and C-H⋯N hydrogen bonds, resulting in dimers forming nine-membered rings of gra ...[more]
