To a solution of 2-chloro-1-[4-(4-fluoro-benzyl)-(2R,5S)-2,5-dimethyl-piperazin-1-yl]-ethanone (0.75 g, 2.50 mmol) in dry dimethylformamide (25 mL) was added potassium iodide (0.40 g, 2.39 mmol), 2-(5-chloro-2-hydroxy-benzyl)-isoindole-1,3-dione (0.80 g, 2.76 mmol) and potassium carbonate (0.70 g, 5.10 mmol). The resulting mixture was heated to 70° C. for 23 hours. The reaction was cooled to ambient temperature, diluted with water and extracted with 1:1 diethyl ether/hexanes (3×). The organic layers were combined, washed with water and brine, dried over magnesium sulfate, filtered and evaporated to give the title compound (0.87 g).
