The title compound, C(23)H(18)ClN(3)O, was synthesized by the reaction of 4-chloro-aniline and 4-benzoyl-3-methyl-1-phenyl-1H-pyrazol-5(4H)-one. The terminal benzene rings are twisted at dihedral angles of 48.3 (2), 71.4 (2) and 36.1 (2)° with respect to the central eight-atom methyl-pyrazolone/amino-methyl-ene unit. An intra-molecular N-H⋯O hydrogen bond stabilizes the planar conformation [mea...
