Procedure

To 3-methoxy-6-nitro-9H-carbazole (100 mg, 0.41 mmol) in 40 mL MeOH was added Palladium on activated carbon (50 mg). The mixture was stirred at rt under H2 atmosphere for 5 h. Solid was filtered off and the filtrate was concentrated to afford 6-methoxy-9H-carbazol-3-amine as a brown solid (80 mg, 92%). This material was used directly for the next reaction without purification. MS (ESI) m/z 213 (M+H+).
