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

Participants

Reaction Steps

A suspension of 7-chloro-1H-pyrrolo[2,3-c]pyridine (650 mg, 4.2 mmol) and Pd/C (10%, 50 mg) in EtOH (25 mL) was stirred at RT under H2 atmosphere (balloon pressure). The reaction mixture was filtered through a celite pad, and the filter cake was washed with EtOAc (10 mL). The filtrate was concentrated and purified via flash chromatography (DCM/MeOH/NH4OH, 9/1/0.1), affording 1H-Pyrrolo[2,3-c]pyridine as a white solid (380 mg, 75% yield).
