چکیده
In the title compound, C(17)H(18)N(2)O(3), the benzene rings form a dihedral angle of 3.34 (2)°. There is a strong intra-molecular O-H⋯N hydrogen bonds (which induces planarity of the structure). In the crystal, mol-ecules are linked by pairs of O-H⋯N hydrogen bonds, forming inversion dimers.
