참여 물질

반응 조건

반응 단계

Triethylamine (13.7 mL, 98 mmol) was added to a solution of tetrahydro-3-furanmethanol (10.0 g, 98 mmol) in methylene chloride (100 mL) at 0° C. followed by addition of methanesulfonyl chloride (12.3 g, 108 mmol) dropwise. The reaction mixture was stirred at 0° C. for 1 h and then allowed to warm to ambient temperature and stirred overnight. Aqueous hydrochloric acid (1N, 100 mL) was added and the two layers were separated. The organic layer was washed with 1N aqueous hydrochloric acid (100 mL×2), saturated aqueous sodium bicarbonate (100 mL×3), and brine (50 mL×1), respectively. The organic phase was dried over anhydrous sodium sulfate and concentrated to afford crude mesylate of tetrahydro-3-furanmethanol.
