To a mixture of 3-(2-(5-bromo-3-phenoxypyridin-2-ylamino)thiazol-4-yl)propanehydrazide (0.150 g, 0.345 mmol) in THF (5 mL) was added TEA (0.04814 mL, 0.3454 mmol) and cooled in an ice bath. To this mixture was added. CDI (0.0672 g, 0.414 mmol) in one portion. The mixture was allowed to warm to ambient temperature and was then heated at 50° C. overnight. The reaction was concentrated to dryness, dissolved in CH2Cl2 and washed with water, dried over Na2SO4, concentrated to a residue that was purified by preparative HPLC to give the title compound (0.045 g, 28.31% yield) was white solids. 1H NMR (d6 DMSO) δ 2.91 (s, 4H), 6.75 (s, 1H), 7.10 (d, J=7.8 Hz, 2H), 7.21 (t, J=7.4 Hz, 1H), 7.40 (d, J=2.1 Hz, 1H), 7.44 (t, J=7.9 Hz, 2H), 8.22 (d, J=2.1 Hz, 1H), 11.03 (br s, 1H), 12.04 (br s, 1H).
