Reaction Steps
Using a procedure analogous to Example A1, 4-(2-chloropyridin-4-yloxy)-3-fluoroaniline (3 g, 11.6 mmol), 1-methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole (3.4 g, 16.4 mmol), Na2CO3 (2.7 g, 25.2 mmol) and Pd(Ph3)4 (1.5 g, 0.1 eq) were combined to give 3-fluoro-4-(2-(1-methyl-1H-pyrazol-4-yl)pyridin-4-yloxy)aniline (1.1 g, 34% yield). 1H NMR (400 MHz, DMSO-d6): δ (8.31 (d, J=5.6 Hz, 1H), 8.22 (s, 1H), 7.93 (s, 1H), 7.14 (s, 1H), 6.98 (m, 1H), 6.55-6.49 (m, 2H), 6.42 (d, J=7.2 Hz, 1H), 5.44 (s, 2H), 3.86 (s, 3H); MS (ESI) m/z: (M+H+): 285.2.
