Ethyl 4-[2-(3,5-dimethyl-4-oxo-2,6-diphenylpiperidin-1-yl)-2-oxoethyl]piperazine-1-carboxylate

Abstract

In the title compound, C28H35N3O4, 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 molecular conformation is stabilized by a weak intramolecular C—H...N interaction and the crystal packing is stabilized by weak intermolecular C—H...O interactions.
