To a solution of 4,4,4-trifluorobutan-1-ol (100 mg, 83 mmol) in dry DCM (2 mL) was added methanesulfonyl chloride (107.3 mg, 72 mmol) and then by TEA (158 mg, 216 mmol) at 0° C. The reaction was stirred at room temperature for 1 h. The reaction was partitioned between ethyl acetate and water. The organic phase was washed with brine, dried over sodium sulfate, filtered and concentrated to give a yellow oil product (50 mg, 31.1% yield), which was used without purification.
