The title compound, C22H26N2O2, crystallizes with three independent mol­ecules, two of which are situated on inversion centers, so the asymmetric unit contains two independent half-mol­ecules and one mol­ecule in a general position. The two hy­droxy groups in each mol­ecule are involved in intra­molecular O—H...N hydrogen bonds, which generate S(6) rings. In the crystal, weak inter­molecular C—H...π inter­actions link the mol­ecules into two crystallographically independent columns propagating along [001]; one column consists of mol­ecules in general positions, while the other column is built from alternating independent centrosymmetric mol­ecules.
