The title compound, C(13)H(14)N(2)O(2)S, crystallized with two independent mol-ecules in the asymmetric unit. They both have V-shaped conformations: the dihedral angles between their benzene rings are identical [45.86 (13)°] and their C-S-N-C torsion angles are similar [67.9 (3) and 70.2 (3)°]. In the crystal, the mol-ecules are linked by N-H⋯O and N-H⋯N hydrogen bonds, generating a three-dimensional network.
