Reaction Steps

A mixture of 2-chloro-4-(cyclopropyl(4-methoxybenzyl)amino)imidazo[2,1-f][1,2,4]triazine-7-carbonitrile (Intermediate 9) (47.4 mg, 0.134 mmol), 3-amino-4-chloro-5-((1-(3-methyloxetan-3-yl)piperidin-4-yl)oxy)benzonitrile (43 mg, 0.134 mmol), palladium(II) acetate (7.95 mg, 0.035 mmol), xantphos (7.73 mg, 0.013 mmol), DPPF (7.41 mg, 0.013 mmol) and cesium carbonate (113 mg, 0.347 mmol) in dioxane (2 ml) was evacuated and back filled with nitrogen three time and was heated at 80° C. for 6 h. The reaction mixture was filtered through a pad of celite, the filtrate was concentrated and the crude was purified by prep-HPLC. 2-((2-chloro-5-cyano-3-((1-(3-methyloxetan-3-yl)piperidin-4-yl)oxy)phenyl)amino)-4-(cyclopropyl(4-methoxybenzyl)amino)imidazo[2,1-f][1,2,4]triazine-7-carbonitrile (35 mg) was obtained.
