Reaktionsschritte

A round-bottom flask was charged with 4-nitroindole (4.8 g, 30 mmol), Palladium on carbon (10%, 480 mg), and THF (50 mL), and the mixture was stirred under one hydrogen atmosphere overnight. TLC showed the reaction was complete. The catalyst was filtered off and the filtrate was concentrated to afford 4-amino-1H-indole, which was used directly in the next step without purification.
