Sodium Iodide → Iodomethyl (2,3,4,5-tetrahydrofurfuryl) carbonate

온도

60 °C

Chloromethyl (2,3,4,5-tetrahydrofurfuryl) carbonate (3.4 g) and sodium iodide (10.46 g) were added to acetonitrile (70 ml), and then the mixture was heated with stirring at 60° C. for 90 minutes. After the reaction solution was cooled, the solvent was distilled off under reduced pressure, and the residue was partitioned between ether (70 ml) and a saturated sodium chloride aqueous solution (50 ml). The organic layer was washed with an aqueous 5% sodium thiosulfate solution (50 ml), water (50 ml) and a saturated sodium chloride aqueous solution (50 ml) successively, and then dried over anhydrous magnesium sulfate. The solvent was distilled off under reduced pressure to obtain iodomethyl (2,3,4,5-tetrahydrofurfuryl) carbonate (4.8 g) as a pale yellow oily product.
