In the title compound, C(18)H(17)N(5)OS, the mean plane of the pyrazole ring [maximum deviation = 0.0031 (12) Å] forms dihedral angles of 19.6 (4) and 9.3 (5)° with the two disorder components of the N-bound benzene ring (with equal occupancies for the two orientations) and a dihedral angle of 72.58 (8)° with the C-O-bonded benzene ring. The mol-ecule exists in a trans conformation with respect to the N=C bond [1.2792 (19) Å]. The mol-ecular structure features an intra-molecular C-H⋯O hydrogen bond, forming an S(6) ring. In the crystal, N-H⋯N and N-H⋯S hydrogen bonds result in the formation of zigzag layers lying parallel to (10-1).
