The reaction mixture is stirred for additional 30 minutes in the ice-bath, then for 45 minutes at room temperature. The reaction mixture is treated with water, acidified with citric acid and extracted 3 times with dichloromethane. The organic phase is dried and evaporated. Chromatography (silica gel, ethyl acetate/hexane 1:1) yields 98 mg (32%) of the title compound as a colorless solid. MS: m/e=318.2 (M++H).
