Mol-ecules of the the title compound, C(21)H(24)Cl(2)N(2)O(2), are located on a twofold rotation axis, which passes through the C atom linking the two N atoms. Two intra-molecular O-H⋯N hydrogen bonds were observed. In the crystal, non-classical inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into chains along the a axis. The crystal studied was a racemic twin.
