Coupling on N-Boc-L-valine (I) with 3-bromopropylamine (II) by means of HBTU afforded amide (III). After Boc group cleavage in (III) using trifluoroacetic acid, the resultant amine (IV) was coupled with N-Boc-L-tyrosine (V) to yield the dipeptide amide (VI). Intramolecular cyclization of (VI) to produce the macrocycle (VII) was achieved by treatment with cesium carbonate in the presence of tetrabutylammonium iodide. Subsequent acid cleavage of the Boc protecting group of (VII) furnished the intermediate amine (VIII).
