Combined 6-(4-bromo-5-methoxy-1H-pyrazol-1-yl)-N-(3-methoxypropyl)nicotinamide (60 mg, 0.163 mmol), 3-fluoro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzonitrile (120 mg, 0.488 mmol), PdCl2(dppf)-CH2Cl2 adduct (19.91 mg, 0.024 mmol) and sodium bicarbonate (68.3 mg, 0.813 mmol) in dioxane (0.6 mL) and water (0.15 mL) and heated 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 0 to 80% EtOAc in hexanes to give 6-(4-(4-cyano-2-fluorophenyl)-5-methoxy-1H-pyrazol-1-yl)-N-(3-methoxypropyl)nicotinamide as a white solid. MS m/z 410 [M+H]+.
