Acetonitrile (5 ml) was added to triphenylsulfonium propionate (336 mg; 1.0 mmol) and methyl p-toluenesulfonate (204 mg; 1.1 mmol). The resultant mixture was refluxed for 5 hours while being stirred. The reaction mixture was cooled, and acetonitrile was removed through distillation under reduced pressure. The thus-obtained pale-yellow solid was washed with methylene chloride, and dried under vacuum, to thereby yield 492 mg of triphenylsulfonium p-toluenesulfonate (yield: 85%).
