To THF (50 mL), NaH (1.41 g, 0.032 mmol) was added at room temperature, followed by addition of ((4R,5R)-5-hydroxymethyl-2,2-dimethyl-[1,3]dioxolan-4-yl)-methanol (5.0 g, 0.031 mmol) at room temperature. The mixture was stirred at room temperature for 1 hr. After that, TBSCl (5.11 g, 0.034 mmol) was added at room temperature and stirred at room temperature overnight. The reaction solution was added with saturated aqueous solution of sodium hydrogen carbonate and extracted with ethyl acetate. The organic layer was dried over magnesium sulfate. The residues obtained after concentration under reduced pressure were purified by silica gel column chromatography (ethyl acetate/hexane) to obtain the title compound (8.21 g, 96%).
