Versuchsvorschrift

In a tetrahydrofuran (30 ml) solution of 3,3-dimethyl-4-penten-1-ol (3.6 g), triethylamine (4.1 g) and methanesulfonyl chloride (4.3 g) were added at 0° C., followed by raising the temperature to room temperature and further stirring for 30 minutes. Water was added thereto and the reaction mixture was extracted with ethyl acetate. The organic layer was washed with saturated saline solution, dried over anhydrous magnesium sulfate, filtered and then concentrated under reduced pressure to obtain a crude product (5.7 g) of methanesulfonic acid 3,3-dimethyl-4-pentenyl ester. This crude product was subjected to a subsequent reaction without being purified.
