Versuchsvorschrift

A mixture of (3-nitropyridin-2-yl)phenylamine (2.49 g, 0.0116 mol) and 10% Pd/C (40 mg) in EtOAc (100 mL) was degassed with a stream of nitrogen and then stirred at RT under a hydrogen atmosphere for 16 h. The suspension was then filtered through a pad of Celite® and then the filtrate was concentrated in vacuo affording N2-Phenylpyridine-2,3-diamine as a white solid (2.06 g, 96%). LCMS: RT 1.15 min [M+H]+ 186.0.
