Procedure

To a microwave vial, was added N-(2-chloro-5-fluoropyrimidin-4-yl)-octahydro-5,5-dimethylindolizin-7-amine (Racemic, single diastereomer; 100 mg, 0.335 mmol, 1 equiv), 1-(5-amino-2-(oxetan-3-yloxy)phenyl)-4-methyl-1H-tetrazol-5(4H)-one (Described in: WO2011/068898 120 mg, 0.455 mmol, 1.36 equiv), rac-BINAP (45 mg, 0.0726 mmol, 0.217 equiv), Cs2CO3 (327 mg, 1.00 mmol, 3 equiv), Pd(OAc)2 (7 mg, 0.0291 mmol, 0.0870 equiv), and dioxane (4 ml). The microwave vial was capped and sonicated under vacuum for 5 minutes. The reaction mixture was heated in the microwave at 120° C. for 2 hours. 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 the desired product 1-(5-(5-fluoro-4-(octahydro-5,5-dimethylindolizin-7-ylamino)pyrimidin-2-ylamino)-2-(oxetan-3-yloxy)phenyl)-4-methyl-1H-tetrazol-5(4H)-one (Compound 38) (Racemic, single diastereomer; 90 mg, 51%) as a solid.
