Vorschrift

In 60 g of dichloromethane was dissolved 6.7 g of 4-tert-butoxyphenyldiphenylsulfonium 1,1,3,3,3-pentafluoro-2-benzoyloxypropane-1-sulfonate (PAG4) prepared in Synthesis Example 14. Methanesulfonic acid, 0.1 g, was added to the solution, which was heated and stirred at 40° C. for 3 hours. The organic layer was washed with 30 g of water three times, and concentrated. Diethyl ether was added to the concentrate for crystallization. The crystals were filtered and dried, obtaining the target compound in an amount of 4.9 g.
