To 20 g of dimethylformamide were added 5.4 g (9.0 mmol) of triphenylsulfonium 2-(4-chlorobutyryloxy)-1,1,3,3,3-pentafluoropropane-1-sulfonate synthesized in Synthesis Example 1-20, 1.2 g (11 mmol) of sodium methacrylate, 0.20 g (1.4 mmol) of sodium iodide, and 1 mg of 2,2′-methylenebis(6-t-butyl-p-cresol). The mixture was heated and stirred at 90° C. for 12 hours. The reaction solution was allowed to resume room temperature, after which 50 g of water and 80 g of dichloromethane were added. The organic layer was separated and washed with water whereupon dichloromethane was distilled off under vacuum. The residue was combined with 30 g of methyl isobutyl ketone and washed with water whereupon methyl isobutyl ketone was distilled off under vacuum. The residue was purified by silica gel chromatography. The target compound, triphenylsulfonium 1,1,3,3,3-pentafluoro-2-(4-methacryloyloxy-butyryloxy)-propane-1-sulfonate was obtained as brown oil (4.2 g, yield 72%).
