4-[(Z)-(n-Butyl­amino)(phenyl)methyl­idene]-3-methyl-1-phenyl-1H-pyrazol-5(4H)-one

The title compound, C(21)H(23)N(3)O, exists in an enamine–keto form with the amino group involved in an intra­molecular N—H⋯O hydrogen bond. The dihedral angle between the phenyl rings is 73.59 (6)°. The five-membered ring is nearly planar, the largest deviation being 0.0004 (7) Å, and makes dihedra...

description The title compound, C(21)H(23)N(3)O, exists in an enamine–keto form with the amino group involved in an intra­molecular N—H⋯O hydrogen bond. The dihedral angle between the phenyl rings is 73.59 (6)°. The five-membered ring is nearly planar, the largest deviation being 0.0004 (7) Å, and makes dihedral angles of 4.81 (6) and 69.81 (5)° wth the phenyl rings. In the crystal, pairs of weak C—H⋯O inter­actions link the mol­ecules into centrosymmetric dimers.
