실험 절차
5-[4-(4-Trifluoromethyl-phenyl)-piperazine-1-sulfonyl]-2,3-dihydro-1H-indole (180 mg, 0.44 mmol) was dissolved in dichloromethane (10 mL). DDQ (100 mg, 0.44 mmol) was added and stirred at room temperature for 4 h. The reaction was concentrated and purified by silica gel flash column chromatography (45% ethyl acetate in hexanes) to provide 5-[4-(4-trifluoromethyl-phenyl)-piperazine-1-sulfonyl]-1H-indole (70%) as a white solid. 1H NMR (400 MHz, DMSO-D6) 11.72 (s, 1H), 8.07 (s, 1H) 7.65 (d, 1H), 7.62-7.61 (m, 1H), 7.52-7.48 (m, 3H), 7.04 (d, 2H), 6.71 (m, 1H), 3.40-3.36 (m, 4H), 3.02-2.99 (m, 4H).
