In the title compound, C(16)H(15)N(3)O(3), the dihedral angle between the pyridine and benzene rings is 7.66 (5)°. The crystal packing is consolidated by inter-molecular C-H⋯O and O-H⋯N inter-actions, which link the mol-ecules into zigzag chains propagating along [010]. The chains are further linked into a three-dimensional network by N-H⋯O, C-H⋯N, C-H⋯O and C-H⋯π inter-actions.
