合成路线1
该中间体在本合成路线中的序号：(II)The acetylation of (E)-2'-deoxy-2'-(fluoromethylene)cytidine (I) with acetyl chloride gives the diacetate (II), which is iodinated with iodine and silver trifluoroacetate in dioxane yielding the 5-iodo derivative (III). The hydrogenation of (III) with tritium over Rh/Al2O3 affords the tritiated diacetyl target compound (IV), which is finally hydrolyzed with K2CO3 in methanol.
