合成路线1
该中间体在本合成路线中的序号：(II)By condensation of 3-[3-(chlorocarbonyl)benzoyl]-1-(ethoxymethyl)-5-fluorouracil (I) with 6-benzoyloxy-3-cyano-2-hydroxypyridine (II) by means of triethylamine in refluxing acetonitrile. The starting compounds (I) and (II) are obtained as follows: The reaction of 1-(ethoxymethyl)-5-fluorouracil (III) with isophthaloyl dichloride (IV) by means of triethylamine in refluxing dioxane gives uracil (I). The esterification of 3-cyano-2,6-dihydroxypyridine (V) with benzoyl chloride (VI) by means of triethylamine in dimethylacetamide affords pyridine (II).
