Procedure

To a solution of 2,2,2-trifluoroethanol (5 g, 50.00 mmol) in methylene chloride (20 mL) was added 4-methylbenzene-1-sulfonyl chloride (9.4 g, 49.21 mmol). Triethylamine (15 g, 148.51 mmol) was added and the resulting solution was stirred overnight. Water (50 mL) was added and the resulting solution was extracted with methylene chloride (2×20 mL). The combined organic layers were dried (Na2SO4) and concentrated in vacuo to afford 10 g (78.7%) of 2,2,2-trifluoroethyl 4-methylbenzenesulfonate.
