Reaction Steps
2-chloro-4-(ethyl(4-methoxybenzyl)amino)imidazo[2,1-f][1,2,4]triazine-7-carbonitrile (Intermediate 7)(50 mg, 0.146 mmol), methyl ((3R,4R)-1-(3-amino-5-cyano-2-fluorophenyl)-3-hydroxypiperidin-4-yl)carbamate (46 mg, 0.149 mmol), DPPF (5.66 mg, 10.21 μmol), Cs2CO3 (81 mg, 0.248 mmol), Xantphos (8.44 mg, 0.015 mmol), Palladium(II)Acetate (9.82 mg, 0.044 mmol) and 1,4-dioxane (2 ml) were combined in a microwave vial. The vial was evacuated and backfilled with Nitrogen 3×. The reaction stirred at 100° C. for 3 hr. The reaction mixture cooled to 25° C., diluted with EtOAc and washed with brine and dried (Na2SO4). The solvents were removed and the material purified on silica gel 25% EtOAc in DCM to afford methyl ((3R,4R)-1-(5-cyano-3-((7-cyano-4-(ethyl(4-methoxybenzyl)amino)imidazo[2,1-f][1,2,4]triazin-2-yl)amino)-2-fluorophenyl)-3-hydroxypiperidin-4-yl)carbamate (60 mg)
