Furthermore, 7-benzyloxyindole (404 mg, 1.81 mmol) was hydrogenated over 10% palladium on carbon (40 mg) in EtOH (4.2 mL) at ambient temperature under atmosphere pressure for 6 h. The catalyst was filtered off and washed with EtOH. The filtrate was concentrated to give 7-hydroxyindole as pale purple crystals, which was rapidly and directly used for the next reaction.
