The compound was prepared by solid phase peptide synthesis on a p-methylbenzhydrylamine resin. Attachment of Boc-L-alanine (I) afforded resin (II). Subsequent deprotection of the Boc group of (II) gave the alanine-linked resin (III). Coupling of (III) with Boc-L-proline (IV), followed by Boc group cleavage yielded the dipeptide resin (V). Further coupling of (V) with N-Boc-(2S,3R)-3-amino-2-hydroxy-5-methylhexanoic acid (VI) furnished the tripeptide resin (VI). Finally, deprotection of the Boc group of (VI) and simultaneous cleavage from the resin by treatment with HF provided the title tripeptide amide.
