Coupling between epoxide (I) and amine (II) affords amino alcohol (III). The amino group of (III) is then protected with benzyl chloroformate to provide carbamate (IV). Removal of the N-Boc group of (IV) with trifluoroacetic acid yields amine (V), which is subsequently coupled with N-Boc-L-valine (VI) by means of TBTU to furnish amide (VII). After acidic Boc group cleavage in (VII), the resultant amine (VIII) is acylated by picolinic acid (IX) producing amide (X).

The N-carbobenzoxy group of (X) is then removed by treatment with triflic acid, yielding (XI). Finally, Suzuki coupling of the aryl bromide (XI) with phenylboronic acid leads to the title biphenyl derivative.
