Reaction Steps

A solution of N-cyclopropyl-4-methoxy-5-(6-methyl-5-((2-(1-methyl-1H-pyrazol-4-yl)pyridin-4-yl)oxy)pyridin-2-yl)pyrimidin-2-amine (0.082 g, 0.191 mmol) in acetic acid (2 mL) was treated with HBr (0.087 mL, 0.764 mmol) and heated at 90° C. for 4 h. The mixture was cooled to RT, treated with ice, neutralized with satd. NaHCO3 and extracted with EtOAc (3×). The combined organics were washed with brine, dried over MgSO4, concentrated to dryness, treated with MeCN, sonicated, heated to near-boiling and allowed to stand at RT overnight. The resulting solid was collected via filtration. The combined aqueous washes were filtered, the solid washed with water, dried and combined with the above-isolated solid to afford 2-(cyclopropylamino)-5-(6-methyl-5-((2-(1-methyl-1H-pyrazol-4-yl)pyridin-4-yl)oxy)pyridin-2-yl)pyrimidin-4(3H)-one (35 mg, 44%). 1H NMR (400 MHz, DMSO-d6): δ 11.09 (br s, 1H), 8.68 (s, 1H), 8.35 (d, J=5.7 Hz, 1H), 8.28 (m, 1H), 8.25 (s, 1H), 7.96 (d, J=0.8 Hz, 1H), 7.66 (br s, 1H), 7.52 (d, J=8.6 Hz, 1H), 7.22 (d, J=2.4 Hz, 1H), 6.60 (dd, J=5.7, 2.4 Hz, 1H), 3.84 (s, 3H), 2.73-2.68 (m, 1H), 2.34 (s, 3H), 0.75 (m, 2H), 0.55-0.53 (m, 2H); MS (ESI) m/z: 416.2 (M+H+).
