A mixture of 3-bromo-1-[1-(4-fluorophenyl)-5-isopropylpyrazol-4-yl]pyrrolidin-2-one (0.080 g, 0.22 mmol), 1H-pyrazolo[3,4-b]pyridine-3-carbonitrile (0.045 g, 0.31 mmol) and K2CO3 (0.070 g, 0.50 mmol) in DMF (2.5 mL) was stirred at 60° C. for 1 hr. It was then cooled to room temperature, quenched with water (30 mL) and extracted with EtOAc (100 mL). The organic layer was separated, dried over anhydrous sodium sulfate, concentrated in vacuo and purified by flash chromatography (SiO2, 0˜100% EtOAc/hexanes gradient elution) to give 1-[1-[1-(4-fluorophenyl)-5-isopropyl-pyrazol-4-yl]-2-oxo-pyrrolidin-3-yl]pyrazolo[3,4-b]pyridine-3-carbonitrile (0.085 g, 88%).
