実験手順
In a reaction vial, 5-bromo-1H-pyrrolo[2,3-b]pyridine (55, 287 mg, 1.46 mmol), 2-methyl-propane-1-sulfonic acid (2,4-difluoro-3-formyl-phenyl)-amide (59, 445 mg, 1.60 mmol) and potassium hydroxide (246 mg, 4.38 mmol) are combined with 7 mL of methanol and stirred at room temperature overnight. The reaction was combined with ethyl acetate and aqueous saturated sodium chloride, and extracted. The organic layer was washed with water, brine, and dried over magnesium sulfate, filtered and the filtrate concentrated under vacuum. The residue was treated with 75 mL of acetonitrile:water 4:1 with 5% trifluoroacetic acid and stirred overnight at room temperature. The reaction was combined with ethyl acetate and aqueous saturated sodium chloride, and extracted. The organic layer was washed with water, brine, and dried over magnesium sulfate, filtered and the filtrate concentrated under vacuum to provide the desired compound (68, 618 mg).
