Mol-ecules of the title compound, C(23)H(30)N(2)O(4), are located on a crystallographic mirror plane. The mol-ecule has a curved shape with the dihedral angle formed between the two benzene rings being 55.26 (5)°. Intra-molecular O-H⋯N hydrogen bonds are noted. In the crystal, supra-molecular layers are formed in the ac plane owing to the presence of C-H⋯π inter-actions.
