Reaction Steps

As shown in the following reaction scheme (2-2), the 1,1-difluoro-2-(2-hydroxy-2-phenylethoxy)ethanesulfonic acid sodium salt produced in Step 1 was allowed to react with diphenyl methylphenyl sulfonium trifluoromethane sulfonate in the same manner as in Step 2 of Synthesis Example 1, and thus 1,1-difluoro-2-(2-hydroxy-2-phenyl-ethoxy)-ethanesulfonic acid diphenyl fluorophenyl sulfonium salt was obtained. Its structure was confirmed by 1H-NMR.
