In the title compound, C20H16ClNO, an S(6) ring motif is formed via an intramolecular C—HO hydrogen bond. The chloro-substituted benzene ring is almost perpendicular to the benzene rings, forming dihedral angles of 87.33 (9) and 88.69 (9)°. The dihedral angle between the benzene rings is 87.17 (9)°. In the crystal, molecules are linked into chains parallel to the c axis by intermolecular N—HO hydrogen bonds. The crystal packing also features weak C—Hπ interactions involving the chloro-substituted ring.
