実験手順

To a solution of 3-nitroso-2-phenyl indole (28) (25 gm, 0.129 mol) in ethanol (450 ml) was added 2N sodium hydroxide (300 mL, 5.0 eq) followed by sodium dithionite (38 g). The reaction was heated at reflux for 5 h, then filtered. The solid was washed with water and dried under vacuum to provide Compound 29 as a yellow solid. Yield=15 g (72.1%). ES-MS: 209.25 (M++1); NMR (DMSO-d6): δ 7.0 (m, 1H), 7.1 (m, 1H), 7.22 (m, 1H), 7.32 (m, 2H), 7.40 (m, 1H), 7.48 (m, 2H), 7.60 (m, 1H).
