To a mixture of 2-{[tert-butyl(dimethyl)silyl]oxy}-3-chloropropyl 4-methylbenzenesulfonate (20.3 g) in acetone (200 mL) was added sodium iodide (19.7 g), and the mixture was stirred at 80° C. for 3 hr. The reaction mixture was concentrated, water was added to the residue, and the mixture was extracted with hexane. The extract was dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (13.4 g).
