In the title mol-ecule, C21H18N2O3, the pyridine rings make a dihedral angle of 13.1 (1)°. The phenyl ring is approximately perpendicular to both of them, forming dihedral angles of 87.4 (1)and 81.9 (1)°. In the crystal, pairs of O-H⋯N hydrogen bonds link the mol-ecules into centrosymmetric dimers. Additional C-H⋯O, π-π [centroid-centroid distance = 3.971 (2) Å] and C-H⋯π inter-actions consolidate the dimers into a three-dimensional network.
