A solution of 2-pyridin-2-yl-4-methyl-pyrimidine-5-carboxylic acid (1.36 mmol), 5-fluoro-3-methyl-pyrrolo[3,2-b]pyridin-1-ylamine (1.36 mmol), DIPEA (158 mg, 4.07 mmol) and HATU (1.63 mmol) in anhydrous DMF (8 mL) is stirred at 90° C. for 15 hours. DMF is evaporated in vacuo. The residue is dissolved in EtOAc (40 mL), washed with water (3×15 mL) and brine (10 mL), dried (Na2SO4), filtered, and concentrated in vacuo. The residue is recrystallized from EtOAc to afford 4-methyl-2-pyridin-2-yl-pyrimidine-5-carboxylic acid (5-fluoro-3-methyl-pyrrolo[3,2-b]pyridin-1-yl)-amide (285 mg) as a solid. MS: 363 (M+H); 1H NMR (300 MHz, CD3OD): δ 2.35 (s, 3H), 2.87 (s, 3H), 6.92 (d, H), 7.51 (s, H), 7.60 (t, H), 7.97 (t, H), 8.05 (t, H), 8.65 (d, H), 8.78 (d, H), 9.23 (s, H).
