The reaction mixture was diluted with EtOAc (50 mL), washed with 1N NaOH (2×25 mL) and brine (60 mL), dried over Na2SO4 and filtered. The filtrate was evaporated under reduced pressure and the residue was purified by silica gel column chromatography (7% EtOAc/hexane) to give the title compound. MS (ESI, pos. ion) m/z: 420 (M+1).
