실험 절차

In 8 g of methanol was dissolved 2.1 g of triphenylsulfonium 4-benzoyloxy-1,1,2,2-tetrafluorobutanesulfonate synthesized in Synthesis Example 9. The solution was stirred under ice cooling, to which 2.5 g of a 9% sodium hydroxide aqueous solution was added dropwise at a temperature below 10° C. The solution was aged at room temperature for 70 hours, after which 22 g of 1N hydrochloric acid was added under ice cooling for quenching the reaction. The methanol was removed under vacuum. Dichloromethane was added to the organic layer, which was washed three times with water. The organic layer was concentrated and dried, obtaining the target compound. Colorless oily matter, 0.3 g.
