In the title compound, C(15)H(21)N(2)O(4), the imidazoline ring displays a twisted conformation. The dihedral angle between the mean plane of the imidazoline ring and the benzene ring is 33.50 (12)°. In the crystal, mol-ecules are connected by O-H⋯O hydrogen bonds, forming a zigzag chain along the c axis. The chains are linked by C-H⋯O and C-H⋯π inter-actions.
