A solution of 4-methoxy-N-methyl-5-(6-methyl-5-((2-(1-methyl-1H-pyrazol-4-yl)pyridin-4-yl)oxy)pyridin-2-yl)pyrimidin-2-amine (0.10 g, 0.25 mmol) in acetic acid (5 mL) was treated with HBr (0.12 mL, 1.0 mmol) and heated at 90° C. for 4 h. The mixture was cooled to RT, quenched with ice water, treated with NaHCO3 and NaCl, and extracted with EtOAc (3×). The combined organics were dried over Na2SO4, concentrated to dryness, the resulting material treated with MeCN (3 mL) and the solid was collected via filtration to afford 5-(6-methyl-5-((2-(1-methyl-1H-pyrazol-4-yl)pyridin-4-yl)oxy)pyridin-2-yl)-2-(methylamino)pyrimidin-4(3H)-one (52 mg, 53%). 1H NMR (400 MHz, DMSO-d6): δ 11.26 (s, 1H), 8.70 (s, 1H), 8.36 (d, J=5.7 Hz, 1H), 8.28 (m, 1H), 8.26 (s, 1H), 7.97 (s, 1H), 7.51 (d, J=8.6 Hz, 1H), 7.22 (d, J=2.4 Hz, 1H), 6.70 (br s, 1H), 6.61 (dd, J=5.7, 2.4 Hz, 1H), 3.85 (s, 3H), 2.85 (d, J=4.7 Hz, 3H), 2.35 (s, 3H); MS (ESI) m/z: 390.2 (M+H+).
