Participants

Reaction Steps

The compound of Example 20 (550 mg, 2.89 mmol), the compound of Example 23 (1.21 g, 2.89 mmol), and potassium carbonate (800 mg, 5.78 mmol) were added to about 25 to 30 ml of DMF. The reaction mixture as stirred at room temperature for 12 hours. The reaction mixture was diluted with ethyl acetate and washed with water. The organic layer was dried over magnesium sulfate and concentrated under vacuum. The crude material was chromatographed on silica gel with 30% ethyl acetate/hexane as eluant. The fractions containing the product were collected and the solvent was removed under vacuum to give the product as a white solid.
