실험 절차

9.2 mg (0.19 mmol) of sodium hydride (50% dispersion in mineral oil) were added to a solution of 50 mg (0.10 mmol) of 5-cyano-3-(2-ethoxypyridin-3-yl)-6-fluoro-2-oxo-2,3-dihydro-1H-indol-3-yl 4-(1-methylpiperidin-4-yl)piperazine-1-carboxylate in 2 ml of anhydrous dimethylformamide under a nitrogen atmosphere and while cooling in an ice bath. The mixture was stirred at 0° C. for 10 min and then 29 mg (0.12 mmol) of 2,4-dimethoxyphenylsulfonyl chloride were added, and stirring was continued at room temperature for 30 min. The reaction mixture was poured into ice-water and then extracted with ethyl acetate. The organic phase was washed with saturated sodium chloride solution and dried over magnesium sulfate, and the solvent was evaporated. The residue was purified by chromatography on silica gel (Redisep cartridge, mobile phase gradient from 0 to 20% methanol in dichloromethane). 34 mg of the title compound were obtained as a white solid.
