Sodium Carbonate → 2-(3-(1H-pyrazolo[3,4-b]pyridin-4-yl)phenyl)-2-methylpropanenitrile

Participants

Reaction Steps

A suspension of 4-iodo-1H-pyrazolo[3,4-b]pyridine (50 mg, 0.204 mmol), 2-methyl-2-(3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)propanenitrile (66 mg, 0.245 mmol), 2 M aqueous solution of sodium carbonate (0.31 ml, 0.612 mmol), tetrakis(triphenylphosphine)palladium(0) (5 mol %, 12 mg, 0.01 mmol), in ethylene glycol dimethyl ether (2.5 ml) was heated under microwave irradiation at 150° C. for 30 minutes. The mixture was cooled down to room temperature, filtered through a path of celite and evaporated to dryness. The residue was partitioned between ethyl acetate and water. The organic phase was dried over magnesium sulfate, filtered and concentrated in vacuo. The residue was purified on silica gel by flash column chromatography to afford the title compound as a white solid (28.4 mg, 53% yield).
