The title compound, 25CH30N2O6, has the imidazolidine ring in an envelope conformation. There are two intramolecular O-H...N hydrogen-bond interactions with graph-set motif S(6). The cyclohexane ring adopts a slightly distorted chair conformation. One methyl carboxylate substituent forms a dihedral angle of 12.00 (5)° with the plane of the benzene ring, while the other methyl carboxylate group is almost coplanar, making a dihedral angle of 2.26 (9)°. In the crystal, pairs of intermolecular C-H...O hydrogen bonds form racemic dimers. Further weak C-H...O interactions generate a chain running along the c axis.
