该中间体在本合成路线中的序号：(XXI)

The amino acid Boc-(2-naphthyl)-D-alanine (XX) were added to intermediate (XIX), yielding the peptide resin (XXI). When the integration of amino acids was completed, the peptide resin (XXI) was deprotected with TFA, acetylated with acetic anhydride and finally treated with ammonia in methanol in order to eliminate the resin matrix and form the final amide group.
