tert-butyl 7-(benzyloxy)-9H-carbazol-2-ylcarbamate → tert-butyl 7-hydroxy-9H-carbazol-2-ylcarbamate

Participants

Reaction Steps

To tert-butyl 7-(benzyloxy)-9H-carbazol-2-ylcarbamate (220 mg, 0.56 mmol) in 50 mL MeOH was added Palladium on activated carbon (80 mg). The mixture was stirred at rt under H2 atmosphere for 3 h. Solid was filtered off and the filtrate was concentrated to afford tert-butyl 7-hydroxy-9H-carbazol-2-ylcarbamate as a brown solid (165 mg, 100%). This material was used directly for the next reaction without purification. MS (ESI) m/z 619 (2M+Na+).
