Abstract: The title molecule, 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 CN group is axial, while the CH₂Ph and NHPh groups are equatorial. The NH group does not engage in strong hydrogen bonding, but forms an intermolecular N-HN interaction.
