To a mixture of 2-fluoro-3-pyridinecarboxylic acid (1.06 g, 7.50 mmol) and HATU (3.11 g, 8.18 mmol) in CHCl3 at ambient temperature under nitrogen was added n,n-diisopropylethylamine (2.38 ml, 13.6 mmol) via syringe. The mixture was allowed to stir for 5 min, at which point 4-(2-(4-aminophenoxy)pyridin-3-yl)-N-methylpyrimidin-2-amine (2.00 g, 6.82 mmol) was added. The reaction was allowed to stir 16 h, resulting in the formation of a fine precipitate. The reaction was filtered, rinsing with 2× dichloromethane and the solid dried in vacuo to give 2-fluoro-N-(4-(3-(2-(methylamino)pyrimidin-4-yl)pyridin-2-yloxy)phenyl)nicotinamide as a tan solid. MS m/z=417 [M+1]+. Calc'd for C22H17FN6O2: 416.41.
