چکیده
In the title compound, C27H29N3O2, the piperidine ring exists in a chair conformation with an equatorial orientation of the phenyl and methyl substituents. The C-C=N bond angles are significantly different [119.1 (2) and 127.2 (2)°]. The phenyl rings are inclined to one another by 44.90 (14)°, and by 80.85 (13) and 79.62 (12)° to the mean plane of the piperidine ring. The terminal pyridine ring is inclined to the piperidine ring mean plane by 74.79 (15)°. In the crystal, mol-ecules are linked by C-H⋯π inter-actions, forming a three-dimensional network.
