合成路线1
该中间体在本合成路线中的序号：(XIV)In a related procedure, aminoethylguanidine (IV) was treated with 1-methyl-4-nitropyrrole-2-carbonyl chloride (XII) producing amide (XIII). Catalytic hydrogenation of the nitro group of (XIII) gave amine (XIV), which was again coupled with acid chloride (XII). The resulting adduct (XV) was then subjected to a new hydrogenation-coupling cycle providing the tripyrrole derivative (X).

合成路线2
该中间体在本合成路线中的序号：(VIII)The reaction of ethylenediamine (I) with Boc2O in dioxane gives the monocarbamate (II), which is condensed with O-methylisourea (III) to yield the aminoguanidine carbamate (IV). The cleavage of the carbamate group of (IV) by means of HCl in methanol affords the aminoguanidine (V), which is condensed with 1-methyl-4-nitropyrrole-2-carbonyl chloride (VI) by means of NaHCO3 in dioxane/water to provide the amide (VII). The reduction of the nitro group of (VII) by means of H2 over Pd/C in 1N HCl affords the 4-aminopyrrole-2-carboxamide (VIII), which is condensed with the acid chloride (VI) as before to give the diamide (IX). Reduction of the nitro group of (IX) under the same conditions described above yields the amino diamide (X), which is condensed with the 14-labeled acid chloride (XI) as described above to afford the triamide (XII). Further reduction of the nitro group of (XII) gives the amino triamide (XIII), which is finally condensed with 4-(2-bromopropenamido)-1-methylpyrrole-2-carbonyl chloride (XIV) by means of NaHCO3 in dioxane/water to yield the target 14C labeled pentaamide compound.
