Procedure

The compound of Example 10 (418 mg, 2.0 mmol), the compound of Example 11 (895 mg, 2.0 mmol), and potassium carbonate (552 mg, 4.0 mmol) were added to 3.0 ml DMF, and the reaction mixture was stirred at room temperature overnight. The reaction mixture was partitioned between ethyl acetate and water. The organic layer was separated, washed with water, and dried over magnesium sulfate. Evaporation of the volatiles afforded a crude oil which was purified by chromatography using 50/50 ethyl acetate/hexane as eluant to give the product as a white solid.
