To a stirred solution of N-(4-(cyclopropyl(6-methoxypyridin-3-yl)methoxy)-3-methoxybenzyl)-5-iodo-3-nitropyridin-2-amine (2.20 g, 3.91 mmol), 1-methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole (0.896 g, 4.30 mmol), and potassium carbonate (1.10 g, 7.95 mmol) in toluene (10 mL) and water (1 mL) was added (1,1′-bis(diphenylphosphino)ferrocene)palladium(II) dichloride (0.143 g, 0.20 mmol). The resulting mixture was heated to 100° C. and stirred under a nitrogen atmosphere. After 16 h, the mixture was allowed to cool to room temperature and was diluted with water (15 mL). The mixture was extracted with ethyl acetate (2×60 mL). The combined organic phases were dried over sodium sulfate, filtered, and concentrated. Chromatographic purification of the residue (silica gel, 33% ethyl acetate in petroleum ether elute) afforded 1.10 g (55%) of N-(4-(cyclopropyl(6-methoxypyridin-3-yl)methoxy)-3-methoxybenzyl)-5-(1-methyl-1H-pyrazol-4-yl)-3-nitropyridin-2-amine as a light brown solid.
