The title ester, C27H30N2O3, crystallizes with two independent molecules in the asymmetric unit whose geometrical features are similar. In each molecule, the pyrrolidine ring adopts an envelope conformation, with the fused C atom shared with the piperidine ring as the flap, and the piperidine ring adopts a chair conformation. In the crystal, C-H interactions link the inversion-related molecules and form a dimeric arrangement in the unit cell.
