title: (Z)-3-Methyl-1-phenyl-4-[(p-tol-yl)(p-tolyl-amino)-methyl-idene]-1H-pyrazol-5(4H)-one.
abstract: In the title mol-ecule, C(25)H(23)N(3)O(2), the pyrazole ring forms dihedral angles of 28.56 (7), 80.35 (7) and 31.99 (7)° with the phenyl ring, the p-tolyl ring and the p-tolyl-amino ring, respectively. The N-H group attached to the exocyclic C=C bond is in a syn arrangement with respect to the C=O bond of the pyrazolone group and an intra-molecular N-H⋯O hydrogen bond is observed. In the crystal, weak C-H⋯π inter-actions link mol-ecules along [100].
