Procedure

1.35 g (11.06 mmol) of (3,3-difluorocyclobutyl)methanol were initially charged in 41.8 ml of abs. dichloromethane, 3.08 ml (22.11 mmol) of triethylamine and 1.03 ml (13.27 mmol) of methanesulphonyl chloride were added and the mixture was stirred at room temperature overnight. Water was added to the reaction mixture and the aqueous phase was extracted twice with dichloromethane. The combined organic phases were washed with saturated aqueous sodium chloride solution, dried over sodium sulphate and filtered, and the filtrate was concentrated. This gave 2.37 g (quantitative yield) of the target compound.
