چکیده
The title compound, C(18)H(21)NO(3), crystallizes in the phenol-imine tautomeric form, with the H atom attached to oxygen rather than on nitro-gen. This H atom is involved in a strong intra-molecular O-H⋯N hydrogen bond. A C-H⋯π inter-action is also present. The dihedral angle between the aromatic rings is 12.23 (7)°.
