There are two independent mol-ecules in the asymmetric unit of the title compound, C(16)H(16)N(2)O(3), in which the dihedral angles between the two aromatic rings are 13.0 (3) and 6.4 (3)°. Intra-molecular O-H⋯N and N-H⋯O hydrogen bonds are observed in both mol-ecules, forming S(6) rings in all cases.
