In the title molecule, C25H21N5, the naphthyridine ring system is almost planar. The phenyl ring planes form dihedral angles of 28.00 (5) and 84.80 (5)° with the attached ring. Conformational disorder is observed in the pyrrolidine ring and both conformers adopt half-chair conformations. In the solid state, the molecules are linked to form centrosymmetrically related hydrogen-bonded dimers.
