There are two mol­ecules in the asymmetric unit of the title compound, C19H22N2O. Both mol­ecules have an E conformation about their C=N bonds and both piperdine rings adopt chair conformations with their N atoms adopting pyramidal geometries [bond angle sums = 329.8 (4) and 330.2 (4)°]. Both mol­ecules feature an intra­molecular O—H...N hydrogen bond, which generates an S(6) ring. The dihedral angles between the phenyl and benzene ring planes are 45.97 (18) and 66.0 (2)°. Short O—H...O contacts occur in the crystal.
