A solution of 48.4 g (0.1 mol) of (p-tert-butoxyphenyl)diphenylsulfonium trifluoromethanesulfonate and 1.5 g (0.01 mol) of trifluoromethanesulfonic acid in 500 g of methanol was heated at 60° to 70° C. for 6 hours with stirring. The reaction mixture was evaporated in vacuo. The residual oil was washed two times with 100 g of diethyl ether. The amount of this crude product was 40 g (yield 93%). Without further purification, the crude product was used in subsequent reaction.
