実験手順
Argon gas was bubbled through a heterogeneous mixture of 2,4-dimorpholino-6-chloropyrimidine (4.1 g, 14.3 mmol) and 4-(trifluoromethyl)-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridin-2-amine (16.5 g, 57.3 mmol) in 1,2-dimethoxyethane and 2M Na2CO3 (3:1) for 20 minutes. 1,1′-Bis(diphenylphosphino)ferrocene palladium(II) chloride (292 mg, 0.36 mmol) was added and the high pressure glass vessel containing the mixture was sealed. The reaction mixture was then heated at 90° C. for 15 hours, cooled and diluted with EtOAc (300 mL). The organic solution was washed with 300 mL of a mixture of water: Na2CO3(sat.):NH4OH(conc.)=5:4:1, then NH4Cl(sat.), and brine (2×), dried over Na2SO4, filtered and concentrated. The crude material was purified by SiO2 chromatography (50-90% EtOAc/hexanes with 0.1% TEA) resulting in 5.62 g (95%) of 4-(trifluoromethyl)-5-(2,6-dimorpholinopyrimidin-4-yl)pyridin-2-amine as an off-white solid. LCMS (m/z): 411.3 (MH+); 1H NMR (CDCl3): δ 8.27 (s, 1H), 6.78 (s, 1H), 5.97 (s, 1H), 4.77 (bs, 2H), 3.59-3.80 (m, 12H), 3.58-3.61 (m, 4H).
