To a microwave vial, was added (7R,8aS)-N-(2-chloro-5-fluoropyrimidin-4-yl)-octahydro-5,5-dimethylindolizin-7-amine hydrochloride (100 mg, 0.298 mmol, 1.00 equiv), 1-(5-amino-4-fluoro-2-(1-hydroxy-2-methylpropan-2-yloxy)phenyl)-4-methyl-1H-tetrazol-5(4H)-one (133 mg, 0.447 mmol, 1.50 equiv), rac-BINAP (38 mg, 0.0597 mmol, 0.200 equiv), Cs2CO3 (292 mg, 0.895 mmol, 3.00 equiv), Pd(OAc)2 (7 mg, 0.0298 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 1-(2-(1-hydroxy-2-methylpropan-2-yloxy)-5-(4-((7R,8aS)-octahydro-5,5-dimethylindolizin-7-ylamino)-5-fluoropyrimidin-2-ylamino)-4-fluorophenyl)-4-methyl-1H-tetrazol-5(4H)-one (compound 85) (85 mg, 51%) as a solid.
