Reaction Steps

Combined 6-(4-bromo-5-methoxy-1H-pyrazol-1-yl)-N-((tetrahydro-2H-pyran-4-yl)methyl)nicotinamide (25 mg, 0.063 mmol), 1-methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridin-2(1H)-one (29.7 mg, 0.127 mmol), PdCl2(dppf)-CH2Cl2 adduct (4.13 mg, 5.06 μmol) and sodium bicarbonate (26.6 mg, 0.316 mmol) in dioxane (0.2 mL) and water (0.05 mL) and heated at 110° C. for 1 h in the microwave. More PdCl2(dppf)-CH2Cl2 adduct (ca. 3 mg), sodium bicarbonate (10 mg) and water (100 uL) was added and the mixture was heated at 110° C. for 1 h in the microwave. The reaction was concentrated onto Celite® purified on 12 g NH silica gel column eluted with 0 to 5% MeOH in methylene chloride to give 6-(5-methoxy-4-(1-methyl-2-oxo-1,2-dihydropyridin-4-yl)-1H-pyrazol-1-yl)-N-((tetrahydro-2H-pyran-4-yl)methyl)nicotinamide as a brown oil (24 mg). MS m/z 424 [M+H]+.
