合成路线1
该中间体在本合成路线中的序号:(III)3-Iodo-L-tyrosine (I) was protected as the N-Boc derivative (II) and subsequently coupled to n-pentylamine yielding amide (III). Palladium-catalyzed carboxylation of the aryl iodide of (III) in the presence of MeOH afforded the methyl ester (IV). The phenolic hydroxyl group of (IV) was then alkylated with methyl bromoacetate under basic conditions to produce diester (V). Acidic Boc group cleavage in (V), followed by acylation of the resulting amine (VI) with N-Boc-L-phenylalanine (VII), generated the dipeptide derivative (VIII). Further deprotection of (VIII) with HCl in dioxane yielded amine (IX), which was finally coupled with succinic acid mono-methyl ester (X) to provide the title compound.
