The title mol-ecule, C19H21N3, an important precursor in the synthesis of porphyrin-fentanyl conjugates, has its piperidine ring in the chair conformation, with endocyclic torsion-angle magnitudes in the range 53.26 (8)-60.63 (9)°. The C N group is axial, while the CH2Ph and NHPh groups are equatorial. The NH group does not engage in strong hydrogen bonding, but forms an inter-molecular N - H⋯N inter-action.
