YieldReaction ConditionsOperation in experiment
70% With chlorosulfonic acid; at 5 - 70℃; 1H-indole-2,3-dione (4.41 g, 30 mmol) was added in portions into chlorosulfonic acid (34.8 g, 300 mmol) below 5 C. The reaction mixture was stirred for another 0.5 h at the same temperature and then the reaction temperature was slowly raised to 70 C and maintained for 3 h. The mixture was cooled and poured into ice, standed still 0.5 h in the ice water, filtrated and the solid was washed with cold water, dried in vacuum oven to afford compound 3 (6.34 g, 70 %). White solid, m.p.: 165-166 C. 1H NMR (400 MHz, CD3COCD3, TMS): delta 8.39(d, J = 2.0 Hz, 1H), 8.23 (dd, J = 8.5, 2.0 Hz, 1H), 7.46 (d, J =8.5 Hz, 1H), 3.29 (s, 1H). IR (KBr, numax, cm-1): 3363, 2963,1767, 1615, 1475, 1359, 1296, 1167, 1124, 1067, 960, 838,714, 595, 511. HR-MS (ESI): Calcd for C8H4NO3SCl3 [M-H]-: 297.8899; found: 297.8897.
