A mixture of 3-(2-(5-bromo-3-phenoxypyridin-2-ylamino)thiazol-4-yl)propanoic acid (0.100 g, 0.238 mmol) (Example 315) HOBT-H2O (0.0547 g, 0.357 mmol), DIEA (d 0.742) (0.0870 mL, 0.500 mmol), EDCI (0.0684 g, 0.357 mmol), and methanamine (0.238 mL, 0.476 mmol) in 10 mL acetonitrile was stirred at ambient temperature for 5 hours and then heated at 50° C. overnight. The mixture was concentrated to a residue, dissolved in THF and precipitated with the addition of water. The solids were filtered, washed with water and dried on high vacuum overnight to give the title compound (0.072 g, 69.8% yield) as white solids. 1H NMR (d6 DMSO) δ 2.41 (t, J=7.8 Hz, 2H), 2.56 (d, J=4.7 Hz, 3H), 2.79 (t, J=7.7 Hz, 2H), 6.62 (s, 1H), 7.10 (d, J=8.0 Hz, 2H), 7.21 (t, J=7.3 Hz, 1H), 7.40 (d, J=2.0 Hz, 1H), 7.43 (t, J=7.9 Hz, 2H), 7.77 (d, J=4.3 Hz, 1H), 8.21 (d, J=2.0 Hz, 1H), 10.94 (br s, 1H).
