In the title compound, C19H22N2O2, the morpholine ring adopts an almost perfect normal chair conformation with puckering parameters Q(T), theta and phi of 0.5642 (18) angstrom, 177.32 (17) and phi = 10 (4)degrees, respectively. The two benzene rings make a dihedral angle of 42.67 (8)degrees with each other. An intramolecular O-H center dot center dot center dot N hydrogen bond helps to stabilize the molecular conformation. Aromatic C-H center dot center dot center dot pi interactions and pi-pi stacking interactions [centroid-centroid distance = 3.6155 (15) angstrom] between the benzene rings contribute to the stabilization of the crystal structure.
