Abstract
The title compound, C23H18ClN3O, exists in an enamine–keto form with the amino group involved in an intramolecular 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 molecules into supramolecular chains along the b axis.
