In the title molecule, C25H21N5, the naphthyridine ring system is almo
st planar. The phenyl-ring planes form dihedral angles of 28.00 (5) an
d 84.80 (5)degrees 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 ce
ntrosymmetrically-related hydrogen-bonded dimers.
