该中间体在本合成路线中的序号：(XIV)

Alkaline hydrolysis of ethyl ester (XII) affords acid (XIII), which is further coupled to ethylamine, producing amide (XIV). Then, removal of the N-Boc group of (XIV) with HCl in EtOAc gives amine (XV). This is coupled to N-Boc-alpha-methylalanine (XVI) to furnish the dipeptide derivative (XVII). Finally, acidic Boc-group cleavage in (XVII) leads to the title compound.
