The title compound, C24H27NO2, crystallizes with two independent molecules (AandB) in the asymmetric unit. The two molecules have very similar conformations and each exhibits an intramolecular C—H...π interaction. The central piperidine rings adopt boat conformations and thep-tolyl rings are inclined to the mean plane of the piperidine ring by 71.21 (11) and 89.86 (12)° in moleculeAand by 68.01 (12) and 89.33 (12)° in moleculeB. The cyclopropanecarbonyl group is oriented at an angle of 68.5 (2)° with respect to the mean plane of the piperidine ring in moleculeAand 66.2 (2)° in moleculeB. In the crystal, theAandBmolecules are linked by C—H...O hydrogen bonds, enclosingR21(6) ring motifs, forming ribbons running along thea-axis direction.
