Description
Summary:	In the title compound, C18H19N3O3S, 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 intermolecular N—H...O and two non-classical intermolecular C—H...O hydrogen bonds are observed in the crystal structure.
