Water → 3,3-Difluorobutyl methanesulfonate

Participants

Reaction Steps

To a solution of 3,3-difluorobutan-1-ol (2.60 g) and triethylamine (6.58 mL) in THF (50 mL) was added dropwise methanesulfonyl chloride (2.74 mL) at 0° C., and the mixture was stirred at room temperature overnight. Water was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The obtained organic layer was washed with saturated brine, and dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (hexane/ethyl acetate) to give the title compound as a pale-yellow oil (2.69 g).
