In the title compound, C25H23N3O3S, an intramolecular N—H.O interaction generates an S(6) ring, which stabilizes the enamine–keto form of the compound.This S(6) ring and the pyrazole ring are essentially coplanar, face exfoliant making a dihedral angle of 1.49 (6)°.

The bond lengths within the S(6) ring of the molecule lie between classical single- and double-bond lengths, indicating extensive conjugation.The Oven Handle End structure exhibits a thienyl-ring flip disorder, with occupancy factors in the ratio 64.7 (3):35.3 (3).
