반응 단계
Combined 6-(4-bromo-5-methoxy-1H-pyrazol-1-yl)-N-(3-methoxypropyl)nicotinamide (50 mg, 0.135 mmol), 2-(2-fluoro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)acetonitrile (70.7 mg, 0.271 mmol), dichloro[1,1′-bis(di-t-butylphosphino)ferrocene]palladium(II) (8.83 mg, 0.014 mmol) and sodium bicarbonate (56.9 mg, 0.677 mmol) in dioxane (0.60 mL) and water (0.150 mL) was heated at 110° C. in the microwave for 40 min. Additional dichloro[1,1′-bis(di-t-butylphosphino)ferrocene]palladium(II) was added (10 mg) and the reaction heated at 110° C. in the microwave for 1 h. The reaction mixture was diluted with EtOAc, concentrated onto Celite®, and purified on a 10 g NH silica gel column eluted with 0 to 100% EtOAc in hexanes to 6-(4-(4-(cyanomethyl)-3-fluorophenyl)-5-methoxy-1H-pyrazol-1-yl)-N-(3-methoxypropyl)nicotinamide (27 mg, 47.1% yield). MS m/z 424 [M+H]+.
