该中间体在本合成路线中的序号：(VII)

The condensation of tert-butoxycarbonyl-L-alanine (I) with benzyl D-isoglutaminate (II) by means of N-hydroxysuccinimide (NOHS) and dicyclohexylcarbodiimide (DCC) gives the protected dipeptide (III), which is hydrogenated with H2 over Pd/C in methanol yielding tert-butoxycarbonyl-D-isoglutaminyl-L-alanine (IV). The condensation of (IV) with Nepsilon-(benzyloxycarbonyl)-L-lysine benzyl ester (V) by means of ethyl chloroformate and triethylamine affords the protected tripeptide (VI), which is treated with trifluoroacetic acid (TFA) to afford L-alanyl-D-isoglutaminyl-(Nepsilon-benzyloxycarbonyl)-L-lysine benzyl ester (VII).
