In the title compound, C29H32N2O2, the piperidine ring exists in a chair conformation (the bond-angle sum at the sp2-hybridized C atom is 359.79°). The phenyl rings and the methyl group substituted on the heterocyclic ring are in equatorial orientations. In the crystal, pairs of C-H interactions result in the formation of inversion dimers.
