실험 절차
40.0 g (0.33 mol) of thionyl chloride are added dropwise at room temperature to a suspension of 12.0 g (0.028 mol) of 3,4,5-trisbenzyloxybenzyl alcohol in 100 ml of diethyl ether. Heating is then carried out at reflux for 2 hours, resulting in a clear solution. After removal of excess thionyl chloride and solvent, the residue is recrystallised from isopropanol/hexane.
