The asymmetric unit of the title compound, C(20)H(18)ClN(5)O(3)S, contains two independent mol­ecules with significantly different conformations of the heterocyclic thia­zine rings. In both mol­ecules, the thia­zine rings adopt half-chair conformations, with the S atoms displaced by 0.382 (3) and 0....

description The asymmetric unit of the title compound, C(20)H(18)ClN(5)O(3)S, contains two independent mol­ecules with significantly different conformations of the heterocyclic thia­zine rings. In both mol­ecules, the thia­zine rings adopt half-chair conformations, with the S atoms displaced by 0.382 (3) and 0.533 (3) Å and N atoms −0.351 and −0.275 Å, respectively, from the planes formed by the remaining ring atoms. The crystal structure is stabilized by weak inter­molecular N—H⋯O and C—H⋯O inter­actions.
