The solvent was evaporated in vacuo. Water (30 mL) and ethyl acetate (40 mL) were added. The layers were separated and the aqueous layer extracted with ethyl acetate. The combined organic extracts were dried (MgSO4) and the solvent evaporated in vacuo. The crude product was purified by flash chromatography (silica gel, dichloromethane, methanol). Yield: 346 mg (1.14 mmol, 37.6%).
