合成路线1
该中间体在本合成路线中的序号：(XVI)In a similar fashion, N-Boc-L-phenylalanine (XI) is coupled with L-valine benzyl ester (XIII) to furnish the protected dipeptide (XIV). Debenzylation of (XIV) with H2 and Pd/C leads to acid (XV), which is then condensed with tripeptide (XII) to yield, after deprotection with formic acid, the pentapeptide derivative (XVI).

合成路线2
该中间体在本合成路线中的序号：(XVI)Coupling of N-Boc-L-leucine (XVII) with glycine benzyl ester (XVIII), followed by acidic N-Boc group cleavage, affords the dipeptide benzyl ester (XIX), which is submitted to coupling with N-Boc-L-isoleucine (XX) and further benzyl ester hydrogenolysis to give rise to the N-Boc tripeptide (XXI). Then, assembly between (XXI) and pentapeptide (XVI) is accomplished by means of EDC/HOBt, providing the protected peptide (XXII). Hydrogenolysis of the benzyl groups of (XXII), followed by Boc group cleavage with trifluoroacetic acid, leads to the fully deprotected octapeptide (XXIII).
