In the title compound, C20H27N3O, the hydroxy group forms an intramolecular O—H⋯N hydrogen bond with the imino N atom. The dihedral angle between the aromatic rings is 33.09 (9)°. In the crystal, molecules form centrosymmetric dimers via pairs of N—H⋯N hydrogen bonds involving aminopyridine fragments.
