Procedure

N-(4-(2-(1,5-Dimethyl-1H-pyrazol-4-yl)pyridin-4-yloxy)-2,5-difluorophenyl)-N′-(4-fluorophenyl)cyclopropane-1,1-dicarboxamide from Example 49 (0.081 g, 0.155 mmol) was dissolved in THF (2.5 ml) and warmed until reflux. Methanesulfonic acid (10.09 μl, 0.155 mmol) was added and the mixture cooled to RT. The mixture was slowly diluted with Et2O (5 ml). A precipitate immediately began to form upon addition. After the addition was complete, the mixture was sonicated for 20 min. The precipitate was filtered off to yield N-(4-(2-(1,5-dimethyl-1H-pyrazol-4-yl)pyridin-4-yloxy)-2,5-difluorophenyl)-N′-(4-fluorophenyl)cyclopropane-1,1-dicarboxamide mesylate (79 mg, 82% yield). 1H NMR (400 MHz, DMSO-d6): δ 11.18 (s, 1H), 9.72 (s, 1H), 8.52 (d, 1H), 8.20-8.14 (m, 2H), 7.63-7.56 (m, 3H), 7.25 (s, 1H), 7.18-7.14 (m, 2H), 6.99-6.94 (m, 1H), 3.74 (s, 3H), 2.35 (s, 3H), 2.28 (s, 3H), 1.67-1.64 (m, 2H), 1.58-1.55 (m, 214); MS (ESI) m/z: 522.2 (M+H+).
