실험 절차

The compound (VII) (13.2 g, 27.8 mmol) is dissolved in Et3N:CHCl3 (1:4, 500 ml) under N2 current and stirred for 16 hours at a room temperature. After the reaction is finished, it is washed by water. An organic layer is dried using anhydrous MgSO4. The solution is vacuum concentrated and then the compound (VIII) (6.37 g, 65%) is isolated using flash column chromatography (toluene/EtOAc, 10:1, v/v).
