The mixture was stirred under a nitrogen atmosphere at 60° C. for 2 hours. The reaction mixture was poured into water (100 ml) and extracted with ethyl acetate (100 ml). The ethyl acetate layer was washed with an aqueous 5% sodium thiosulfate solution (50 ml×2), water (50 ml×2), and a saturated sodium chloride aqueous solution (50 ml). After drying over anhydrous magnesium sulfate, the solvent was distilled off under reduced pressure to obtain [3-(benzyloxy)propyl] iodomethyl carbonate (2.5 g) as a pale yellow liquid.
