该中间体在本合成路线中的序号：(IV)Condensation of 4-chloro-3-nitrobenzenesulfonyl chloride (VII) with L-proline tert-butyl ester (VIII) yielded sulfonamide (IX). Displacement of the chloro group of (IX) with hydrazine hydrate furnished the aryl hydrazine (X), which was reacted with benzhydryl isothiocyanate (XI) to produce the thiosemicarbazide (XII). After acid cleavage of the tert-butyl ester of (XII), the resulting carboxylic acid (XIII) was activated with isobutyl chloroformate and then coupled with triamine (VI) to furnish the title amide.
