Versuchsvorschrift

3-Methoxy-2-nitro-pyridine (53, 7.00 g, 45.4 mmol) in 100 mL of methanol, was degassed and palladium (0.7 g, 20%) was added. The reaction was stirred at room temperature for one day under a hydrogen balloon. The reaction was filtered through celite and the filtrate concentrated under vacuum to provide the desired compound (54, 5.555 g). MS (ESI) [M+H+]+=125.3.
