以(2R,3R,4R,5R)-2-(乙酰氧基甲基)-5-(2-氨基-6-氯-9H-嘌呤-9-基)四氢呋喃-3,4-二基二乙酸酯为原料,合成(2R,3R,4R,5R)-2-(乙酰氧基甲基)-5-(2,6-二氯-9H-嘌呤-9-基)四氢呋喃-3,4-二乙酸二酯的一般步骤如下:将亚硝酸异戊酯(165 g,1.41 mol)溶解于二氯甲烷(500 mL)中,并在0至5°C下搅拌。随后加入三甲基氯硅烷(76 g,0.70 mol),接着加入化合物IV(100 g,0.234 mol)的二氯甲烷(500 mL)溶液。将混合液滴加至上述反应母液中,滴加完毕后,继续在相同温度下搅拌反应1小时。反应完成后,加入饱和亚硫酸钠溶液进行淬灭,分液。分离得到的有机相依次用碳酸氢钠水溶液和饱和盐水洗涤,然后用无水硫酸钠干燥,过滤。将滤液减压浓缩至无馏分蒸出。残余物通过加入二氯甲烷(100 mL)和正庚烷(350 mL)进行重结晶,得到黄色固体化合物V,即2,6-二氯-9-(2',3',5'-三-O-乙酰基-β-D-呋喃核糖基)嘌呤(86 g,产率82%)。
