実験手順

2-chloro-4-(ethyl(4-methoxybenzyl)amino)imidazo[2,1-f][1,2,4]triazine-7-carbonitrile (33.5 mg, 0.098 mmol), (Intermediate 10), (+/−)-3-amino-4-chloro-5-((4aR,8aR)-2-oxohexahydro-1H-pyrido[3,4-b][1,4]oxazin-6(7H)-yl)benzonitrile (30 mg, 0.098 mmol), DPPF (3.8 mg, 6.85 mol), Cs2CO3 (65.4 mg, 0.201 mmol), Xantphos (5.66 mg, 9.78 μmol), palladium(I)Acetate (6.83 mg, 0.029 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 5% MeOH in DCM to afford (+/−)-2-((2-chloro-5-cyano-3-((4aR,8aR)-2-oxohexahydro-1H-pyrido[3,4-b][1,4]oxazin-6(7H)-yl)phenyl)amino)-4-(ethyl(4 methoxybenzyl)amino)imidazo[2,1-f][1,2,4]triazine-7-carbonitrile.
