Procedure
The title compound was prepared using methods analogous to those described in Step C of Example 504 using 4′-(2-aminopyrazin-5-yl)-3′-fluoro-[1,1′-biphenyl]-2-carboxylic acid and (S)-2-aminopropan-1-ol for (S)-1,1,1-trifluoropropan-2-amine. MS (ESI): mass calcd. for C20H19FN4O2, 366.15; m/z found, 367.1 [M+H]+. 1H NMR (400 MHz, DMSO-d6) δ 8.37 (s, 1H), 8.05 (d, J=5.1, 2H), 7.93-7.83 (m, 1H), 7.54-7.43 (m, 3H), 7.37-7.28 (m, 2H), 6.72 (s, 2H), 4.66 (t, J=5.6, 1H), 3.82 (d, J=7.0, 1H), 3.35 (s, 1H), 3.16 (d, J=10.4, 2H), 0.98 (d, J=6.6, 3H).
