Reaction Steps

Using a procedure analogous to Example A3, 4-(2-chloro-pyridin-4-yloxy)-2-fluoro-3-methyl-phenylamine (1.0 g, 3.3 mmol), 1-methyl-4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-1H-pyrazole (1 g, 4.8 mmol), Na2CO3 (0.84 g, 6.6 mmol) and Pd(PPh3)4 (0.25 g, 0.2 mmol) were combined to give 2-fluoro-3-methyl-4-[2-(1-methyl-1H-pyrazol-4-yl)-pyridin-4-yloxy]-phenylamine (0.74 g, 75% yield). 1H NMR (400 MHz, DMSO-d6): δ 8.27 (d, J=6.4 Hz, 1 H), 8.18 (s, 1 H), 7.90 (s, 1 H), 7.07 (s, 1 H), 6.68-6.61 (m, 2 H), 6.45 (dd, J=5.6, 2.4 Hz, 1 H), 5.06 (s, 2 H), 3.89 (s, 3 H), 1.95 (s, 3H); MS (ESI) m/z: 299.2 [M+H]+.
