With stirring at 0° C., 63 ml of methylsulfonyl chloride in 40 ml of toluene are added dropwise to a solution of 69.3 g of 3-trifluoromethyl-1,5-pentanediol and 140 ml of triethylamine in 150 ml of toluene. After 12 hours' stirring at room temperature, the solid portions are filtered off and the toluene solution is concentrated in vacuo to give in almost quantitative yield 1,5-bismethanesulfonyloxy-3-trifluoromethylpentane; m.p. 40°-45° C.
