In the title compound, C(18)H(22)N(2)O(3), the dihedral angle between the aromatic rings is 3.9 (2)°. Both H atoms of the hy-droxy groups are involved in inter-molecular O-H⋯O hydrogen bonding. In the crystal structure, this hydrogen bonding assembles mol-ecules into chains of 2(1) symmetry extending parallel to the b axis. The almost planar (within 0.09 and 0.06 Å) 4-CH(3)O-C(6)H(4)-CH=N-C(6)H(4)- groups are oriented outwards the twofold screw axis.
