HCID 67999125(3R,5R,6S)-3-allyl-5-(3-chlorophenyl)-6-(4-chlorophenyl)-1-(cyclopentylmethyl)piperidin-2-one

Procedure

The title compound was prepared from (3R,5R,6S)-3-allyl-5-(3-chlorophenyl)-6-(4-chlorophenyl)piperidin-2-one (Example 42, Step A) and (bromomethyl)cyclopentane as described in Example 44, Step A. Purification of the residue by silica gel prep plate (25% EtOAc/hexanes) provided the title compound as a colorless solid.
