The imidazolidine ring in the title compound, C(17)H(18)Cl(2)N(2)O(2), adopts a twist conformation. The observed conformation is stabilized by two intra-molecular O-H⋯N hydrogen bonds, with both N atoms acting as hydrogen-bond acceptors. The phenyl substituents are aligned at 70.0 (1) and 76.6 (1)° with respect to the best plane through the five atoms of the imidazolidine ring. Weak inter-molecular C-H⋯O inter-actions stabilize the crystal packing.
