Abstract: The title compound, C₂₁H₂₃N₃O, exists in an enamine-keto form with the amino group involved in an intramolecular N-HO 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-HO interactions link the molecules into centrosymmetric dimers.
