合成路线1
该中间体在本合成路线中的序号：(XVI)The regioselective protection of 4-hydroxymethylimidazole (X) with trityl chloride gave the 1-trityl imidazole (XI), which was further acetylated to afford acetate (XII). Alkylation of imidazole (XII) with 4-cyanobenzyl bromide (XIII), followed by solvolysis of the resulting imidazolium salt in refluxing methanol, produced the cyanobenzyl imidazole (XIV). Acetate hydrolysis and subsequent oxidation of alcohol (XV) furnished aldehyde (XVI). The title compound was obtained by reductive alkylation of piperazinone (IX) with aldehyde (XVI) in the presence of sodium triacetoxyborohydride.

合成路线2
该中间体在本合成路线中的序号：(XXVIII)Peptide resin (XX) was subjected to sequential coupling-deprotection cycles with the following amino acids: N-Boc-(2-thienyl)alanine (XXI), N-Boc-glycine (XXIII), N-Boc-4-hydroxyproline (XXV), N-Boc-proline (XXVII), Nalpha-Boc-Ngamma-tosyl-arginine (XXIX) and Nalpha-Boc-Ngamma-nitro-D-arginine (XXXI) to produce peptide resins (XXII), (XXIV), (XXVI), (XXVIII), (XXX) and (XXXII), respectively. The title peptide was finally obtained by deprotection and cleavage from the resin by means of treatment with HF.
