Abstract: The methyl-substituted imidazolidine ring of the title compound, C24H26N2O2, adopts an envelope conformation with the N atom adjacent to the methylene group as the flap. The methyl-ethylene fragment in this ring is disordered over two positions with an occupancy ratio of 0.899 (4):0.101 (4). The hydroxybenzyl groups are inclined at 71.57 (15) and 69.97 (19)° to the mean plane of major disorder component of the heterocyclic ring with an interplanar angle between the two hydroxybenzyl groups of 66.00 (5)°. The phenyl substituent approaches a nearly perpendicular orientation relative to the mean plane of the imidazolidine ring, making a dihedral angle of 75.60 (12)°. This conformation is stabilized by two intramolecular O-H...N bonds, which generate S(6) ring motifs.
