The resulting solution was stirred at room temperature for 12 h, diluted with a saturated ammonium chloride and extracted with EtOAc. The organic layer was washed with water then brine, dried over anhydrous MgSO4, filtered and concentrated in vacuo. The crude residue was purified by column chromatography (3-10% EtOAc/hexanes) to yield the title compound (17.9 g, 96%) as a colorless oil.
