Coupling between N-Boc-D-(4-chlorophenyl)alanine succinimidyl ester (VI) and L-naphthylalanine methyl ester (VII) affords the protected dipeptide (VIII). The methyl ester group of (VIII) is hydrolyzed by means of LiOH to produce the carboxylic acid (IX), which is subsequently coupled to the di-Boc-protected noragmatine (V), yielding amide (X). Finally, acidic cleavage of the Boc protecting groups of (X) leads to the title compound
