Triethylamine → 6,6-Difluoro-5-methyl-5-hexenyl methanesulfonate

참여 물질

반응 단계

To 100 ml of tetrahydrofuran, 5.00 g (33 mmol) of methyl 6,6-difluoro-5-methyl-5-hexenol and 4.20 g (37 mmol) of methanesulfonyl chloride were dissolved, followed by drop-wisely adding 4.40 g (44 mmol) of triethylamine under ice-cooling. After the end of the drop-wise addition, the reaction liquid was stirred at room temperature for 1 hour. Hydrochloric acid salt of triethylamine was filtered, followed by adding water to the filtrate and extracting with ethyl acetate. The organic layer was washed with water and a saturated saline solution in this order, followed by drying over anhydrous magnesium sulfate and concentrating under reduced pressure to obtain 7.50 g (yield: 99%) of 6,6-difluoro-5-methyl-5-hexenyl methanesulfonate.
