7-Chloro-1H-pyrrolo[2,3-c]pyridine → 6-Azaindole

Participants

Reaction Steps

Hydrogenation of 7-chloro-1H-pyrrolo[2,3-c]pyridine (10 mmol) was carried out in the presence of Pd—C (10%) in EtOH (50 mL). After stirred at room temperature for 20 hrs, the mixture was filtered through a pad of celite 521. The residue was washed with EtOH several times. The filtrate was evaporated to yield 1H-pyrrolo[2,3-c]pyridine as brown oil. MS (ESI+) m/z 119.0657 (M+H)+.
