In the title compound, C(17)H(15)N(3)O(4)S, the five-membered isoxazole ring makes dihedral angles of 80.5 (2) and 81.3 (2)° with the two benzene rings, which form a dihedral angle of 39.81 (18)° with each other. A short intra-molecular C-H⋯O contact occurs. The crystal structure is stabilized by inter-molecular N-H⋯O hydrogen bonds, which generate [001] chains, and further consolidated by weak C-H⋯O inter-actions.
