Procedure
A similar procedure as described for preparation of 77 from 5-nitro-2-indolecarboxylic acid ethyl ester (0.8 g, 3.41 mmol) and N-propylethylenediamine (2 ml) gave a brown solid (0.84 g, 85%). ESI MS: 291.13 (M+H+). 1H NMR (DMSO-d6) δ 8.68 (d, 1H), 8.04 (d, 1H), 7.55 (d, 1H), 7.37 (s, 1H), 3.35 (m, 3H), 2.68 (q, 2H), 2.49 9 (q, 2H), 1.40 (tt, 2H), 0.84 (t, 3H).
