실험 절차

Ethyl 5-(2-methoxyethoxy)-7-{[(1-methyl-1H-imidazol-2-yl)sulfonyl]amino}-1H-indole-2-carboxylate (780 mg) was dissolved in N,N-dimethylformamide (10 mL), potassium carbonate (256 mg) and methyl iodide (0.15 mL) were added, and the mixture was stirred at room, temperature for 15.5 hr. Water was added to the reaction solution, and the mixture was extracted with ethyl acetate. The organic layer was washed successively with aqueous sodium thiosulfate solution and saturated brine, dried over magnesium sulfate, and filtrated, and the filtrate was concentrated under reduced pressure. The obtained crude product was subjected to basic silica gel column chromatography (ethyl acetate:hexane=10:90-40:60) to give the title compound (740 mg, yield 92%) as a colorless oil.
