该中间体在本合成路线中的序号：(XIV)Treatment of D-tryptophan methyl ester (XI) with N,N'-disuccinimidyl carbonate (XII) gave the intermediate succinimidyl carbamate (XIII), which was subsequently converted to urea (XV) upon reaction with spiro(indene-1,4'-piperidine) (XIV). Saponification of the ester function of (XV) with LiOH afforded the carboxylic acid (XVI), and this was then coupled with the Boc-protected chiral diamine (X) using EDC and HOBt. The resulting precursor (XVII) was finally deprotected with HCl in EtOAc to provide the title compound.
