合成路线1
该中间体在本合成路线中的序号:(VI)4-Nitrobenzylamine (I) is protected as the corresponding trifluoroacetamide (II) and subsequently reduced to aniline (III) by catalytic hydrogenation over Pd/C. Condensation of (III) with N,N'-di-Boc-N''-(trifluoromethanesulfonyl)guanidine (IV) furnishes the Boc-protected guanidine (V). The trifluoroacetamide function of (V) is then hydrolyzed by means of K2CO3 in aqueous MeOH to provide amine (VI). (1,2)

合成路线2
该中间体在本合成路线中的序号:(VI)Acylation of O-t-butyl-D-serine methyl ester (VII) with sulfonyl chloride (VIII) yields sulfonamide (IX). After saponification of the methyl ester group of (IX) employing LiOH, the resultant carboxylic acid (X) is coupled to L-alanine t-butyl ester (XI) to furnish the sulfonyl dipeptide (XII). Acidic cleavage of the t-butyl ester group of (XII) gives rise to the carboxylic acid (XIII). This is then coupled to the benzylic amine (VI) to afford amide (XIV). Finally, the N-Boc protecting groups of (XIV) are removed by treatment with trifluoroacetic acid in CH2Cl2. (1,2)
