The reaction mixture was stirred at room temperature for 72 h and then filtered through celite, washing with dichloromethane. The filtrate was concentrated in vacuo and the residue was purified by flash chromatography (silica gel, ethyl acetate/heptane gradient) to afford 34 mg (17%) of the title compound as a pink oil. MS (ISP): 226.3 ([M+H]+).
