合成路线1
该中间体在本合成路线中的序号:(V)Several procedures for obtaining titte compound have been reported: In one method the acylation of 1 naphthylamine 4,6,8-trisulfonic acid trisodium salt (I) with 4 methyl-3-nitrobenzoyt chloride (II) yields the correspond ing amide (III), which is reduced with Fe in acetic acid to the amine (IV). Acylation of (IV) with 3-nitrobenzoyl chloride (V) affords the nitro diamide (VI), which is reduced with Fe and acetic acid before to the amine (VII). Finally, this compound is condensed with phosgene.

合成路线2
该中间体在本合成路线中的序号:(II)The Friedel-Crafts condensation of indole (I) with 3-nitrobenzoyl chloride (II) by means of AlCl3 in dichloromethane gives 3-(3-nitrobenzoyl)indole (III), which is allowed to react with ethyl 4-bromobutyrate (IV) by means of K2CO3 in DMF to yield 4-[3-(3-nitrobenzoyl)indol-1-yl]butyric acid ethyl ester (V). The hydrolysis of (V) with NaOH in dioxane/water affords the corresponding butyric acid (VI), which is hydrogenated with H2 over Pd/C in methanol/dioxane yielding 3-[3-(3-aminobenzoyl)indol-1-yl]butyric acid (VII). Finally, this compound is condensed with bis(4-isobutylphenyl)chloromethane (VIII) by means of ethyldiisopropylamine in dichloromethane.
