title: 1,5-Dimethyl-2-phenyl-4-[phenyl(pyri-din-2-ylamino)methyl]-1H-pyrazol-3(2H)-one.
abstract: In the title compound, C(23)H(22)N(4)O, the pyrazole ring makes dihedral angles of 45.57 (11)° with the attached phenyl ring, and 83.98 (10) and 67.85 (10) °, respectively, with the other phenyl ring and the pyridyl ring. The pyridyl ring makes a dihedral angle of 80.15 (10)° with the adjacent phenyl ring. In the crystal, N-H⋯O hydrogen bonds supplemented by weak C-H⋯O hydrogen bonds link the mol-ecules into chains which run parallel to the a-axis direction.
