In the title compound, C17H18N2O4, the dihedral angle between the two benzene rings is 6.0 (2)° and the molecule adopts an E configuration with respect to the C=N bond. There is an intramolecular O—H⋯O hydrogen bond in the molecule, which generates an S(6) ring. In the crystal, molecules are linked through intermolecular N—H⋯O hydrogen bonds, forming C(4) chains running along the c axis.
