Reaction Steps

A suspension of (5-methoxy-3-nitro-pyridin-2-yl)-acetonitrile (Maybridge, 986 mg, 5.1 mmol) and Pd/C (10%, 986 mg) in EtOH/EtOAc (95/5, 50 mL) was shaken for 6 hours under H2 (60 PSI) in Parr apparatus. The reaction mixture was then filtered through a celite pad, and the filter cake was washed with EtOAc (20 mL). The filtrate was concentrated, and the residue was dissolved in EtOAc (50 mL), washed with NaHCO3 (saturated solution, 50 mL), dried over MgSO4, filtered, concentrated, and purified via flash chromatography (hexane/EtOAc), affording 5-Methoxy-1H-pyrrolo[3,2-b]pyridine as a white solid (720 mg, 95% yield).
