Participants

Reaction Steps

500 mg (2.05 mmol) of the above product 3 is taken as the starting material, and dissolved in 35 mL of pyridine. Then 11 ml of acetic anhydride is added with continuously stirring. The solution is concentrated under reduced pressure by removing the residual part of the solution after the completion of the reaction, and then purified by rapid column chromatography (acetone/n-hexane=4:5). A white product (1-(2′,3′,5′-Tri-O-acetyl-β-D-arabinofuranosyl)-pyrimidin-2,4-(3H)-dione) 4 is obtained. Its weight and yield are 675 mg and 89% respectively.
