It was then partitioned between water and ethyl acetate, and the aqueous layer was extracted with ethyl acetate (3*15 mL). The combined organic layers were dried over magnesium sulfate, filtered, and concentrated in vacuo. Silica gel chromatography (Gradient: 0% to 25% ethyl acetate in heptane) provided the product as an oil. Yield: 71 mg, 0.13 mmol, 62%.
