Palladium-catalyzed coupling of methyl (3-bromophenyl)acetate (I) with 2-pyridyl triflate (II) furnished the pyridylphenylacetate ester (III), which was further hydrolyzed with LiOH to the corresponding carboxylic acid (IV). Coupling of acid (IV) with (3S)-3N-Boc-1,3-diamino-2-butanol (V) using HBTU produced amide (VI). After acid cleavage of the Boc protecting group of (VI), the resulting amine (VII) was coupled with N-Boc-leucine (VIII), yielding adduct (IX). Subsequent acidic deprotection of (IX) provided the intermediate amine (X).
