合成路线1
该中间体在本合成路线中的序号:(II)Coupling of thiazolopyridine (I) with amine (II) in the presence of EDC and HOBt provided amide (III). Deprotection of the Fmoc group of (III) was effected with piperidine in CH2Cl2 and the resulting amine (IV) was condensed with benzylsulfonyl chloride (V) to afford sulfonamide (VI). Finally, both Boc protecting groups of (VI) were removed with TFA to yield the title guanidine as the bis(trifluoroacetate) salt.

合成路线2
该中间体在本合成路线中的序号:(V)1,3-Diaminopropane (I) is mono-protected with benzyl chloroformate, producing carbamate (II). Coupling of (II) with N,N'-bis-Boc-S-methylisothiourea (III) yields the Boc-protected guanidine (IV). The benzyloxycarbonyl group of (IV) is then removed by catalytic hydrogenolysis to furnish the noragmatine derivative (V)

合成路线3
该中间体在本合成路线中的序号:(V)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
