To 62 g of dichloromethane were added an amount (corresponding to 0.031 mole) of the triphenylsulfonium chloride aqueous solution of Synthesis Example 1 and 1.1 g (0.033 mole) of sodium 1,1-difluoro-2-tosyloxyethanesulfonate synthesized in Synthesis Example 9, followed by stirring. The organic layer was separated and washed with 20 g of water three times. The organic layer was concentrated and 10 g of diisopropyl ether was added to the residue for crystallization. The crystals were filtered and dried, obtaining the target compound. White crystals, 1.3 g (yield 74%).
