Procedure

2-chloro-4-(cyclopropyl(4-methoxybenzyl)amino)imidazo[2,1-f][1,2,4]triazine-7-carbonitrile (100 mg, 0.282 mmol), 5-amino-4-chloro-2-(4-oxopentan-2-yl)benzonitrile (67 mg, 0.282 mmol), palladium (II) acetate (18.9 mg, 0.085 mmol), DPPF (15.6 mg, 0.028 mmol), Xantphos (16.3 mg, 0.028 mmol), and cesium carbonate (184 mg, 0.564 mmol) were combined in a 10 dram vial and dioxane (2 mL) was added. The vial was evacuated and backfilled with N2 3×, then heated at 90° C. for 1 h. The reaction was cooled to room temperature and the reaction mixture was filtered through celite, rinsing with EtOAc. The solvent was removed in vacuo and the material was purified by ISCO Companion (0-100% EtOAc/Hexane). 2-((2-chloro-5-cyano-4-(4-oxopentan-2yl)phenyl)amino)-4-(cyclopropyl(4-methoxybenzyl)amino)imidazo[2,1-f][1,2,4]triazine-7-carbonitrile (97 mg) was obtained as a yellow foam.
