DMAP (cat.) was added and the reaction was stirred at room temperature for 4 h. After no further progress of the reaction was observed (monitored by TLC and LCMS), water was added and the mixture was extracted with DCM. The organic phase was washed with a sat. KHSO4 solution, dried (Na2SO4) and concentrated in vacuo. The crude residue was triturated with n-hexane to give the title compound (270 mg, 61%).
