title: 1,5-Dimethyl-4-{[1-(3-methyl-5-oxo-1-phenyl-4,5-dihydro-1H-pyrazol-4-yl-idene)eth-yl]amino}-2-phenyl-1H-pyrazol-3(2H)-one.
abstract: In the title compound, C(23)H(23)N(5)O(2), an intra-molecular N-H⋯O hydrogen bond generates an S(6) ring, and the dihedral angle between the pyrazole rings is 48.42 (8)°. The dihedral angles between the pyrazole rings and their attached phenyl rings are 10.06 (8) and 47.53 (8)°.
