실험 절차

A solution of 4-(5-amino-2-(2,4-difluorophenoxy)phenyl)-6-methyl-1-tosyl-1H-pyrrolo[2,3-c]pyridin-7(6H)-one (4.35 g, 8.34 mmol) in dichloromethane (50 mL) was cooled to 0° C. To this solution was added ethanesulfonyl chloride (2.37 mL, 25.0 mmol). The reaction mixture was stirred at room temperature for 2 hours. The solvent was evaporated, and the residue was partitioned between ethyl acetate and water. The aqueous layer was extracted with additional ethyl acetate twice. The combined organic layers were washed with saturated aqueous sodium chloride, dried over anhydrous magnesium sulfate, filtered, and concentrated. The residue was purified by flash chromatography (silica gel, 80% ethyl acetate/hexanes) to provide N-(4-(2,4-difluorophenoxy)-3-(6-methyl-7-oxo-1-tosyl-6,7-dihydro-1H-pyrrolo[2,3-c]pyridin-4-yl)phenyl)-N-(ethylsulfonyl)ethanesulfonamide (5.34 g, 91% yield).
