To a microwave vial, 4-acetyl-2-methylphenyl trifluoromethanesulfonate (34-1) (40 mg, 0.14 mmol), [1-(2,2-dimethylpropyl)-3-methyl-2-oxo-2,3-dihydro-1H-imidazo[4,5-b]pyridin-5-yl]boronic acid (14-1) (56 mg, 0.22 mmol), cesium carbonate (92 mg, 0.28 mmol), CuCl (14 mg, 0.14 mmol), and Bis(diphenylphosphino)ferrocene dicholoropalladium (8 mg, 0.015 mmol) was added under nitrogen and dissolved in DMF (0.7 ml). The suspension was heated overnight at 100° C. The reaction was cooled to room temperature, diluted with methanol, and passed through a syringe filter. The solution was purified using reverse phase chromatography (10-100%, 0.1% TFA in H2O/Acetonitrile) and the desired fractions were collected and concentrated to produce 5-(4-acetyl-2-methylphenyl)-1-(2,2-dimethylpropyl)-3-methyl-1,3-dihydro-2H-imidazo[4,5-b]pyridin-2-one (34-2). MS (M+H)+: observed=352.3, calculated=352.4.
