The 2-aminobenzophenone derivative (III) was prepared by condensation of L-tyrosine methyl ester (I) with 2-benzoylcyclohexanone (II) in refluxing anisole, with concomitant dehydrogenation in the presence of Pd/C. Subsequent Mitsunobu coupling of (III) with 2-(N-Boc-N-methylamino)ethanol (V), prepared from aminoalcohol (IV) and Boc2O, afforded the Boc-protected aminoethyl ether (VI). After removal of the Boc group of (VI) by treatment with trifluoroacetic acid, condensation of the resulting secondary amine (VII) with 2-fluoropyridine (VIII) yielded the 2-aminopyridine derivative (IX). Finally, the methyl ester group of (IX) was hydrolyzed to the title carboxylic acid using LiOH.
