Procedure

5-[1,2,4]Triazol-1-yl-1H-indole-2,3-dione was prepared from 4-11,2,4]-triazol-1-yl-phenylamine according to Procedure A in 6% yield: 1H NMR (DMSO-d6): δ 7.04 (d, J=8.4 Hz, 1H), 7.97 (d, J=2.2 Hz, 1H), 8.01 (dd, J=2.2, 8.4 Hz, 1H), 8.20 (s, 1H), 9.26 (s, 1H), 11.19 (bs, 1H); APCI−MS m/z 215 (M+1)+. Condensation of 5-[1,2,4]triazol-1-yl-1H-indole-2,3-dione with 4-hydrazino-N-methyl-phenylsulfonamide according to Procedure G gave the title compound in 86% yield: 1H NMR (DMSO-d6): δ 2.38 (d, J=5.0 Hz, 3H), 7.05 (d, J=8.4 Hz, 1H), 7.30 (q, J=5.0 Hz, 1H), 7.65 (d, J=8.7 Hz, 2H), 7.72 (d, J=8.7 Hz, 3H), 8.01 (s, 1H), 8.20 (s, 1H), 9.23 (s, 1H), 11.27 (s, 1H), 12.80 (s, 1H); Anal. Calcd for C16H15N7O3S.1.3 H2O: C, 48.52, H, 4.22; N, 23.30; S, 7.62. Found C, 48.53, H, 4.25; N, 23.17; S, 7.55.
