PROCEDURE

实验过程

[(3aR,4R,6R,6aR)-6-(6-Chloro-9H-purin-9-yl)-2,2-dimethyltetrahydrofuro[3,4-d][1,3]dioxol-4-yl]methanol (1.000 g, 0.003060 mol), pyridine (495.1 μL, 0.006121 mol), 4-dimethylaminopyridine (0.0748 g, 0.000612 mol) and acetic anhydride (577.5 μL, 0.006121 mol) were stirred in methylene chloride (20 mL) at room temperature for 1 h. The solution was diluted with Methylene chloride, extracted with HCl 1N, dried over NA2SO4 and concentrated in vacuo. The residue was purified by flash chromatography (EtOAc/DCM 0% to 25%) to obtain the product (1.129 g, 84%) as an oil.
