Abstract
In the title compound, C21H26N2O2, the dihedral angle between the two benzene rings is 73.47 (16)°. Strong intramolecular O—H⋯N hydrogen bonds generate S(6) ring motifs. The substituted benzene rings are twisted around the central quaternary C atom in opposite directions, making a vault geometry.
