In the title compound, C(32)H(26)Cl(2)N(2)O(3), the piperidone ring adopts a chair conformation and the proline and pyrrolidine rings adopt envelope conformations. The indane ring system is essentially planar with an r.m.s. deviation of 0.011 Å for the non-H atoms. The dihedral angle between the two chloro-substituted benzene rings is 63.69 (10)°. Intra-molecular C-H⋯O and N-H⋯O hydrogen bonds may influence the mol-ecular conformation. In the crystal structure, mol-ecules are connected into layers by weak inter-molecular C-H⋯O hydrogen bonds.
