Procedure

2-[3-(3,4-Dichloro-phenyl)-1-(3-methoxy-benzoyl)-pyrrolidin-3-yl]-ethyl-methanesulfonate (0.54 g), 4-phenyl-piperidine-4-carboxylic acid amide hydrochloride (173 mg, 0.72 mmol) and potassium carbonate (0.25 g, 1.8 mmol) were combined in THF/H2O (20 mL/10 mL) and heated at reflux for 48 hours. The reaction mixture was diluted with ethyl acetate and extracted with water. The organic layer was separated, dried over MgSO4, and evaporated in vacuo to give a residue. The residue was chromatographed on silica gel eluting sequentially with 1% methanol in dichloromethane, 2% methanol in dichloromethane, 3% methanol in dichloromethane, 6% methanol in dichloromethane, and 10% methanol in dichloromethane to give the title compound: Rf =0.48 (silica gel, 10% methanol in dichloromethane).
