Procedure

The compound of Example 10 (200 mg, 0.96 mmol), the compound of Example 23 (400 mg, 0.96 mmol) and potassium carbonate (264 mg, 1.92 mmol) were added to about 20 ml of DMF. The reaction mixture was stirred at room temperature overnight. The reaction mixture was diluted with ethyl acetate and washed with water. The organic layer was dried over magnesium sulfate and concentrated under vacuum. Chromatography of the crude material on silica gel with 30% ethyl acetate/hexane as eluant followed by rechromatography using the same solvent system gave the product.
