合成路线1
该中间体在本合成路线中的序号:(IV)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).

合成路线2
该中间体在本合成路线中的序号:(I)Reaction of isophthaloyl dichloride (I) with cycloheptylamine (II) in the presence of triethylamine in dichloromethane gives N,N'-dicycloheptylisophthalimide (III), which is reduced with sodium bis(2-methoxyethoxy)aluminum hydride in toluene to yield 1,3-bis(cycloheptylaminomethyl)benzene (IV). Compound (IV) is treated with p-nitrophenylisocyanate (V) to afford 1,3-bis[1-cycloheptyl-3-(4-nitrophenyl)ureidomethyl]benzene (VI), which is reduced with hydrogen in the presence of palladium over charcoal to give 1,3-bis[1-cycloheptyl-3-(4-aminophenyl)ureidomethyl]benzene (VII). Finally, compound (VII) is treated with aqueous formaldehyde and hydrogen in the presence of platinum oxide in ethanol, followed by addition of hydrochloric acid in ethanol.
