Versuchsvorschrift
A solution of 4-methoxy-5-(6-methyl-5-((2-(1-methyl-1H-pyrazol-4-yl)pyridin-4-yl)oxy)pyridin-2-yl)-2-(pyrrolidin-1-yl)pyrimidine (0.1 g, 0.22 mmol) in acetic acid (3 mL) was treated with HBr (0.1 mL, 0.90 mmol) and heated at 90° C. for 6.5 h. The mixture was cooled to RT, quenched with ice water, neutralized with NaHCO3 to pH=8 and extracted with EtOAc (3×). The combined organics were dried over Na2SO4, concentrated to dryness, the resulting material treated with MeCN 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-(pyrrolidin-1-yl)pyrimidin-4(3H)-one (89 mg, 91%). 1H NMR (400 MHz, DMSO-d6): δ 11.21 (s, 1H), 8.73 (s, 1H), 8.36 (d, J=5.7 Hz, 1H), 8.31 (m, 1H), 8.26 (s, 1H), 7.97 (d, J=0.7 Hz, 1H), 7.52 (m, 1H), 7.22 (d, J=2.4 Hz, 1H), 6.61 (d, J=5.6 Hz, 1H), 3.85 (s, 3H), 3.50 (m, 4H), 2.35 (s, 3H), 1.91 (m, 4H); MS (ESI) m/z: 430.2 (M+H+).
