実験手順

To a microwave vial, was added 4-((7R,8aS)-octahydro-5,5-dimethylindolizin-7-ylamino)-2-chloropyrimidine-5-carbonitrile hydrochloride (100 mg, 0.292 mmol, 1.00 equiv), 1-(5-amino-4-fluoro-2-(1-hydroxy-2-methylpropan-2-yloxy)phenyl)-4-methyl-1H-tetrazol-5(4H)-one (130 mg, 0.438 mmol, 1.50 equiv), rac-BINAP (37 mg, 0.0584 mmol, 0.200 equiv), Cs2CO3 (286 mg, 0.877 mmol, 3.00 equiv), Pd(OAc)2 (7 mg, 0.0292 mmol, 0.100 equiv), and dioxane (3 mL). The microwave vial was capped and sonicated under vacuum for 5 min. The reaction mixture was heated in the microwave at 120° C. for 3 h. The cooled reaction mixture was filtered using a pad of celite and rinsed with dioxane, and the filtrate was concentrated. The crude product was purified by flash chromatography and eluted with DCM:2M NH3/MeOH=100:0 to 95:5 using 1% 2M NH3/MeOH increments to provide 4-((7R,8aS)-octahydro-5,5-dimethylindolizin-7-ylamino)-2-(4-(1-hydroxy-2-methylpropan-2-yloxy)-2-fluoro-5-(4,5-dihydro-4-methyl-5-oxotetrazol-1-yl)phenylamino)pyrimidine-5-carbonitrile (compound 84) (65 mg, 39%) as a solid.
