چکیده
In the title compound, C22H26N4O3S, the dihedral angle between the pyrazoloneand phenyl rings is 21.73 (4)°. The benzensulfono-hydrazide group adopts a gauche conformation about the N-N vector. The C-N-N-S torsion angle is -109.88 (13)°. The mol-ecule exists as the enamine tautomeric form (C=C-NH). An intra-molecular N-H⋯O=C hydrogen bond occurs. In the crystal, mol-ecules are linked by pairs of N-H⋯O=C hydrogen bonds, forming centrosymmetric dimers.
