The non-H atoms of the title mol­ecule, C19H16N2O2, are almost coplanar (r.m.s. deviation = 0.019 A), apart from the phenyl group, which is disordered with two components of almost equal occupancy: the dihedral angle between them is 78.9 (3)°. In the crystal, weak C—H⋯N hydrogen bonds link the mol­ecules into [001] chains and aromatic π–π stacking inter­actions [shortest centroid–centroid separation = 3.747 (2) A] form columns parallel to the c-axis direction.
