Vorschrift
A suspension of 1-(5-((2-chloropyridin-4-yl)oxy)-6-methylpyridin-2-yl)-3-cyclopropyl-1H-1,2,4-triazol-5(4H)-one (0.285 g, 0.829 mmol), 1-methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole (0.250 g, 1.202 mmol), Cs2CO3 (0.600 g, 1.842 mmol) and Pd(PPh3)4 (0.050 g, 0.043 mmol) in MeCN (20 mL) was heated at 100° C. under argon for 4 hours. The solvent from the reaction mixture was completely evaporated and the residue was partitioned between DCM (50 mL) and water (50 mL). The organic layer was separated and the aqueous layer saturated with solid sodium chloride and extracted with DCM (2×20 mL). The combined organics were dried, concentrated, and purified by silica gel chromatography (0-20% MeOH/DCM) to provide 3-cyclopropyl-1-(6-methyl-5-((2-(1-methyl-1H-pyrazol-4-yl)pyridin-4-yl)oxy)pyridin-2-yl)-1H-1,2,4-triazol-5(4H)-one (0.228 g, 66%) as a white solid. 1H NMR (400 MHz, dmso): δ 11.80 (s, 1H), 8.36 (d, J=5.7 Hz, 1H), 8.26 (s, 1H), 7.96 (s, 1H), 7.86 (d, J=8.8 Hz, 1H), 7.68 (d, J=8.8 Hz, 1H), 7.20 (d, J=2.4 Hz, 1H), 6.63 (dd, J=5.7, 2.4 Hz, 1H), 3.84 (s, 3H), 2.32 (s, 3H), 1.87 (tt, J=8.4, 5.1 Hz, 1H), 0.95 (m, 4H); MS (ESI) m/z: 390.2 (M+H+).
