title: Ethyl 4-[2-(3,5-dimethyl-4-oxo-2,6-diphenyl-piperidin-1-yl)-2-oxoeth-yl]piperazine-1-carboxyl-ate.
abstract: In the title compound, C(28)H(35)N(3)O(4), the piperidine ring adopts a boat conformation while the piperazine ring adopts a chair conformation with an equatorial orientation of the phenyl groups. The dihedral angle between the mean planes of the benzene rings is 74.14 (8)°. The mol-ecular conformation is stabilized by a weak intra-molecular C-H⋯N inter-action and the crystal packing is stabilized by weak inter-molecular C-H⋯O inter-actions.
