実験手順
Combined 6-(4-bromo-5-methoxy-1H-pyrazol-1-yl)-N-((tetrahydro-2H-pyran-4-yl)methyl)nicotinamide (80 mg, 0.202 mmol), N,N-dimethyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridin-2-amine hydrochloride (173 mg, 0.607 mmol), PdCl2(dppf)-CH2Cl2 adduct (16.53 mg, 0.020 mmol) and sodium bicarbonate (136 mg, 1.619 mmol) in dioxane (0.6 mL) and water (0.15 mL) was let stir for 15 min. The mixture was then capped and heated at 110° C. for 1 h in the microwave. Additional PdCl2(dppf)-CH2Cl2 adduct (17 mg) was then added and the heating continued at 110° C. for 1 h in the microwave. The reaction mixture was diluted with EtOAc, concentrated onto Celite® and purified on a 10 g NH silica gel column eluted with 10 to 100% EtOAc in hexanes to give 64442-(dimethylamino)pyridin-4-yl)-5-methoxy-1H-pyrazol-1-yl)-N-((tetrahydro-2H-pyran-4-yl)methyl)nicotinamide as a brown oil. MS m/z 437 [M+H]+.
