Reaction Steps
A mixture of 2-chloro-4-(cyclopropyl(4-methoxybenzyl)amino)imidazo[2,1-f][1,2,4]triazine-7-carbonitrile (40 mg, 0.113 mmol), 3-amino-4-chloro-5-(4-methyl-2-oxopiperazin-1-yl)benzonitrile (28 mg, 0.106 mmol), palladium(ii) acetate (12 mg, 0.053 mmol), XANTPIIOS (12 mg, 0.021 nmmol), DPPF (12 mg, 0.022 mmol) and cesium carbonate (90 mg, 0.275 mmol) in Dioxane (1.5 mL) was evacuated and back filled with nitrogen three time and was heated at 80° C. for 3 h. LC-MS showed reaction was complete. The reaction mixture was filtered through a pad of Celite, rinsed with EtOAc and the filtrate was concentrated and purification via flash chromatography (0-70% EtOAc in Hexane, 24 g) gave 2-((2-chloro-5-cyano-3-(4-methyl-2-oxopiperazin-1-yl)phenyl)amino)-4-(cyclopropyl(4-methoxybenzyl)amino)imidazo[2,1-f][1,2,4]triazine-7-carbonitrile (60 mg) as a light oil.
