Procedimiento

Into a glass flask equipped with a thermometer and a capacitor were charged the aqueous solution of sodium 2-(2,4-bis(methoxycarbonyl)cyclopentyl)-1,1,2,2-tetrafluoroethanesulfonate obtained as described above, and 1.31 g (4.38 mmol) of triphenylsulfonium chloride, and the mixture was stirred at room temperature for 6 hrs. Thereafter, the reaction liquid was extracted with 30 mL of dichloromethane three times, and the resultant organic layer was washed with 100 mL of water six times. Distillation of dichloromethane in vacuo gave 1.51 g of triphenylsulfonium 2-(2,4-bis(methoxycarbonyl)cyclopentyl)-1,1,2,2-tetrafluoroethanesulfonate (compound (A-1)) represented by the following formula (A-1).
