实验步骤: To propane-2-sulfonic acid (2,4-difluoro-3-formyl-phenyl)-amide (60, 220.0 mg, 0.83 mmol) in methanol (15 mL) was added 5-pyridin-3-yl-1H-pyrrolo[2,3-b]pyridine (89, 150.0 mg, 0.77 mmol, prepared as described in Example 17) and potassium hydroxide (537.0 mg, 9.6 mmol) under an atmosphere of nitrogen. The reaction was stirred at room temperature overnight. The reaction was poured into water and extracted with ethyl acetate. The organic layer was washed with brine, dried over sodium sulfate and filtrated. The filtrate was concentrated and purified by silica gel column chromatography eluting with 5% methanol in dichloromethane to give the compound (61, 160 mg, 45.3%). In this step, minor compound Propane-2-sulfonic acid {2,4-difluoro-3-[methoxy-(5-pyridin-3-yl-1H-pyrrolo[2,3-b]pyridin-3-yl)-methyl]-phenyl}-amide was also formed and isolated. MS (ESI) [M+H+]+=460.1. extracted with ethyl acetate The organic layer was washed with brine dried over sodium sulfate filtrated The filtrate was concentrated purified by silica gel column chromatography eluting with 5% methanol in dichloromethane to give the compound (61, 160 mg, 45.3%)
