    In the crystal structure of the title compound, C21H24F2N2O2, the two N atoms of the imidazolidine moiety are linked to the hydroxy groups by intramolecular O-H...N hydrogenbonding interactions. The crystal studied was a racemic mixture of RR and SS enatiomers. The cyclohexane ring adopts a chair conformation and the imidazolidine group to which it is fused has a twisted envelope conformation.
