Tetrahydrofurfuryl alcohol (19.4 g) was dissolved in anhydrous ether (500 ml) and, after adding pyridine (15 g) under ice cooling, chloromethyl chloroformate (25 g) was added dropwise. After the reaction mixture was stirred at room temperature for 17 hours, the deposited pyridine hydrochloride was removed by filtration and the filtrate was washed with ether (50 ml×2). The washings and the filtrate were combined, washed with water (300 ml×2) and then dried over anhydrous magnesium sulfate. The solvent was distilled off under reduced pressure to obtain chloromethyl (2,3,4,5-tetrahydrofurfuryl) carbonate (33.9 g) as a colorless oily product.
