Versuchsvorschrift

In 6 g of Eaton's reagent (Aldrich, diphosphorus pentoxide/methanesulfonic acid solution) was dispersed 2.4 g (0.0107 mol) of 1-(2,2,2-trifluoroethoxy)naphthalene in Synthesis Example 1-3. With stirring, 2.2 g (0.0214 mol) of tetramethylene sulfoxide was added dropwise to the dispersion. The solution was matured overnight at room temperature and combined with 30 g of water and 30 g of diisopropyl ether, from which a water layer was separated. The water layer was again washed with 30 g of diisopropyl ether. This aqueous solution was combined with an aqueous solution of triethylammonium 1,1,3,3,3-pentafluoro-2-(4-oxoadamantane-1-carbonyloxy)-1-propanesulfonate (corresponding to 0.0086 mol) synthesized in accordance with the teaching of JP-A 2008-106045, after which extraction was effected twice with 50 g of dichloromethane. The organic layer was washed with water, distilled in vacuum to remove the solvent, and dried, obtaining the target compound. Amorphous solids, 5.2 g, yield 84%.
