Reaction Steps

To the reaction mixture of 5-bromo-4-fluoropyridin-2-amine (369 mg, 1.932 mmol), 1-methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole (603 mg, 2.90 mmol), PdCl2(dppf)DCM (141 mg, 0.193 mmol) and DME (9.660 μL), 2M Na2CO3 (3.220 mL) was added. The reaction mixture was heated at microwave synthesizer (120° C., 12 min). To the reaction mixture, anhydrous sodium sulfate was added, filtered, and concentrated. The crude product was purified by flash chromatography eluting with 0-100% EtOAc (containing 10% of MeOH/heptane to provide 280 mg of desired product in 75% yield. LCMS (m/z): 193.1 (MH+), 0.35 min.
