In the title compound, C(26)H(24)N(4)O(2), the dihedral angles between the central pyrazole ring and the other three benzene rings are 40.02 (3), 77.51 (5) and 55.72 (3)°. A strong intra-molecular N-H⋯O hydrogen bond forms a six-membered ring with an S(6) motif. In the crystal structure, a weak inter-molecular C-H⋯N inter-action with graph-set motif R(2) (2)(8) and C-H⋯O hydrogen bonds link each mol-ecule to three others, forming an infinite two-dimensional supra-molecular structure.
