The reaction mixture was warmed to RT and stirred at RT for 2 h. The reaction mixture was stripped to dryness, mixed with ice-cooled HCl (1M), extracted with EtOAc, washed with brine, dried over MgSO4, filtered and concentrated. The residue was purified with flash chromatography (silica gel, 2:1 hexane/EtOAc) to give the title compound.
