A mixture of 4-(1-(5-bromopyrimidin-2-yl)piperidin-4-yloxy)-1-(4-(methylsulfonyl)phenyl)pyridin-2(1H)-one (103 mg, 0.20 mmol), potassium carbonate (140 mg, 1.02 mmol, EMD) and prop-1-en-2-ylboronic acid (52.4 mg, 0.610 mmol) in DMF (1.8 mL) and Water (0.2 mL) was degassed by vacuum and purged with Argon. To the resulting mixture was added 1,1′-Bis(diphenylphosphino)ferrocene-palladium(II)dichloride dichloromethane complex (16.72 mg, 0.020 mmol, Aldrich) and then heated under microwave conditions at 120° C. for 20 min. The reaction mixture was concentrated in vacuo to a brown solid. The solid was purified by flash chromatography (SiO2, 0 to 100% EtOAc in hexanes) to yield 25 mg of desired product as a light yellow solid. MS (ESI) 467 (M+H).
