Abstract: In the title molecule, C₁₇H₂₀N₂O₂, the imidazolidine ring adopts a twist conformation. The mean plane through the five atoms of the imidazolidine ring makes dihedral angles of 70.18 (4) and 74.14 (4)° with the planes of the two aromatic rings. The dihedral angle between the benzene rings is 53.11 (5)°. Both phenol -OH groups form intramolecular hydrogen bonds to the N atoms, with graph-set motif S(6). In the crystal, pairs of O-HO hydrogen bonds link the molecules into dimers with R₄⁴(18) ring motifs. The crystal packing is further stabilized by C-HO and weak C-H interactions.
