Versuchsvorschrift

A solution of tetrahydrofuran-3-ol (25.0 g, 283 mmol) in 150 ml of DCM was cooled to 0° C., to this was added triethylamine (59 ml, 425 mmol) and mesylchloride (26.0 ml, 340 mmol), stirred the reaction mixture for 4 h at room temperature. TLC indicated reaction completion, it was diluted with DCM (100 ml), washed with water and brine solution, dried over anhydrous sodium sulfate, organic layer was evaporated to yields (44.0 g) of title product which was used as such for the next step.
