Acid (XV) was coupled with protected amino acid (XVI) to give amide (XVII), and the Boc protecting group of (XVII) was then removed under acidic conditions. The resulting amine (XVIII) was condensed with cyclopentyl chlorothioformate (XIX) to provide thiocarbamate (XX). Finally, the title compound was obtained by trifluoroacetic acid-promoted cleavage of the trityl protecting group of (XIX).
