실험 절차

2,3-Dioxo-2,3-dihydro-1H-indole-5-sulfonyl chloride (0.10 g, 0.41 mmol), prepared by the reaction of the sodium salt of 5-isatinsulfonic acid with POCl3, was dissolved in 5 mL THF. This solution was cooled in an ice bath and DIEA (0.14 mL, 2.0 eq) was added slowly, followed by n-propylamine (35 uL, 1.0 eq). Stirring was continued for 40 min and the solution was diluted with ethyl acetate and washed with brine. The organic layer was dried over Na2SO4 and the solvent was removed by evaporation. The residue was purified by SiO2 chromatography to give the title compound (65 mg, 60%).
