In the title compound, C(19)H(25)NO(2), the dihedral angle between the benzene rings is 53.15 (8)°. One of the -OH groups forms an intra-molecular O-H⋯N link, generating an S(6) ring. The other -OH group forms an inter-molecular O-H⋯N hydrogen bond in the crystal, generating centrosymmetric R(2) (2)(20) loops.
