title: N-(1,5-Dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazol-4-yl)-4-methyl-benzene-sulfonamide.
abstract: In the title compound, C(18)H(19)N(3)O(3)S, the phenyl ring and the pyrazole ring are twisted with respect to each other by an angle of 49.11 (7)°. The C-N-S-C torsion angle is -122.5 (2)°. The methyl group bonded to the N atom of the pyrazole ring has a large deviation from the mean ring plane of 0.603 (3) Å. One inter-molecular N-H⋯O and two non-classical inter-molecular C-H⋯O hydrogen bonds are observed in the crystal structure.
