Procedure

The compound of Example 6 (465 mg), the compound of Example 3 (1 g) and potassium carbonate (312 mg) were added to 5.0 ml of dimethylformamide (DMF), and the reaction mixture was stirred at room temperature for about 2 days. Water (20 ml) was added and the reaction mixture was extracted three times with ethyl acetate and the combined extracts washed twice with water, dried and filtered. Solvent was removed under vacuum to give an oil. Chromatography of the oil on silica gel with 20/80 ethyl acetate/hexane gave the product as a white solid.
