The reaction mixture was then heated to 80° C. for 1.5 hours. The solution was cooled to room temperature, diluted with ether (50 mL), washed with water (3×5 mL), brine, dried over MgSO4, and concentrated under reduced pressure. The residue was chromatographed eluting with ethyl acetate/hexanes (1:1) to afford 0.070 g of product (47% yield).
