Reaction Steps

A solution of 4-methoxy-5-(4-methyl-5-((2-(1-methyl-1H-pyrazol-4-yl)pyridin-4-yl)oxy)pyridin-2-yl)-2-(pyrrolidin-1-yl)pyrimidine (0.19 g, 0.43 mmol) in acetic acid (2.5 mL) was treated with HBr (48%, 0.10 mL, 1.8 mmol) and heated at 90° C. for 16 h. The mixture was poured onto ice (10 g), neutralized with satd. NaHCO3, and the resulting solid was collected by filtration, washed with water and MeCN and dried to afford 5-(4-methyl-5-((2-(1-methyl-1H-pyrazol-4-yl)pyridin-4-yl)oxy)pyridin-2-yl)-2-(pyrrolidin-1-yl)pyrimidin-4(3H)-one (0.11 g, 58%). 1H NMR (400 MHz, DMSO-d6): δ 11.22 (bs, 1H), 8.68 (s, 1H), 8.38 (s, 1H), 8.34 (d, J=5.7 Hz, 1H), 8.30 (d, J=1.3 Hz, 1H), 8.26 (s, 1H), 7.96 (s, 1H), 7.22 (d, J=2.4 Hz, 1H), 6.60-6.58 (m, 1H), 3.84 (s, 3H), 3.50 (bs, 4H), 2.15 (s, 3H), 1.91 (bs, 4H); MS (ESI) m/z: 430.2 (M+H+).
