In the title compound, C(25)H(23)N(3)O(2), the dihedral angles formed by the pyrazolone ring with the three aromatic rings are 14.59 (7), 79.35 (5) and 87.10 (6)°. Three intra-molecular C-H⋯O, C-H⋯N and N-H⋯O hydrogen-bond inter-actions are present. The crystal structure is stabilized by two weak inter-molecular C-H⋯O and C-H⋯N hydrogen-bond inter-actions.
