Procedure

N6-benzoyl-5′-O-(tert-butyldimethylsilyl)-2′-deoxyadenosine (16.1 g) was dissolved in 100 ml of anhydrous pyridine. 4,4′-dimethoxytrityl chloride (12.8 g) and anhydrous pyridine (140 ml) were further added, follow by stirring at 45° C. After the reaction completed, the reaction mixture was neutralized by sodium hydrogen carbonate, and pyridine was distilled off. Extraction using chloroform was carried out and the extract was washed by a saturated aqueous solution of sodium chloride and dried with anhydrous magnesium sulfate. The extract was concentrated and then purified by column chromatography (ethyl acetate/hexane) to obtain 16.7 g of the titled compound (yield: 63%).
