(4Z)-4-[(2-Chloro-anilino)(phen-yl)methyl-idene]-3-methyl-1-phenyl-1H-pyrazol-5(4H)-one.

ABSTRACT: The title compound, C(23)H(18)ClN(3)O, exists in an enamine-keto form with the amino group involved in an intra-molecular N-H?O hydrogen bond. The five-membered ring is nearly planar, the largest deviation being 0.0004?(7)?Å, and makes dihedral angles of 16.62?(6), 41.89?(5) and 71.27?(4)° with the phenyl rings. In the crystal, weak C-H?O hydrogen bonds link the mol-ecules into supra-molecular chains along the b axis.

Project description: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 [mean deviation = 0.0398?(5)?Å] of the central unit, generating an S(6) ring motif. The crystal packing is stabilized by van der Waals forces.
