실험 절차

A solution of 1-(4-fluorophenyl)-1H-pyrazolo[3,4-c]pyridine-4-carboxylic acid [(S)-1-(2-bromo-pyridin-4-yl)-2-cyano-ethyl]-amide (122 mg, 0.262 mmol), sodium methanesulfinate (53.5 mg, 0.524 mmol) and copper (I) iodine (99.8 mg, 0.524 mmol) in DMSO (2.5 mL) was evacuated and purged with argon three times and warmed at 130° C. After 45 minutes, the reaction was cooled to room temperature and N,N′-dimethylethylenediamine (112 μL, 1.05 mmol) was added. The mixture stirred for 30 minutes and was then diluted with ethyl acetate (20 mL), stirred for 15 minutes, and saturated aqueous ammonium chloride (20 mL) was added. The mixture was sonicated for 30 minutes, and was then diluted with ethyl acetate (100 mL). The aqueous layer was separated and extracted with ethyl acetate (2×20 mL). The combined organic layers were washed with saturated aqueous ammonium chloride (2×50 mL), saturated aqueous sodium bicarbonate (50 mL), brine (50 mL), dried over MgSO4, filtered and concentrated. The resulting residue was purified by silica gel chromatography eluting with a gradient of 0-8% methanol in CH2Cl2. The solid was further purified by HPLC using a C18 column and a gradient of 5-95% acetonitrile+0.1% TFA and water+0.1% TFA to afford the title compound. MS m/z 465.68 (MH+).
