Versuchsvorschrift

(R)-Tetrahydrofuran-3-ol 1a (300 mg, 3.40 mmol) and triethylamine (687 mg, 6.80 mmol) were dissolved in 20 mL of dichloromethane in an ice bath, followed by addition of methanesulfonyl chloride (468 mg, 4.10 mmol). The reaction solution was warmed up to room temperature and stirred for 2 hours. The reaction solution was mixed with 10 mL of dichloromethane, washed with water (30 mL×3), dried with anhydrous magnesium sulphate, and filtered. The filtrate was concentrated under reduced pressure to obtain the title compound (R)-tetrahydrofuran-3-yl methanesulfonate 1b (520 mg) as a yellow oil, which was directly used in the next step without further purification.
