N-ethyl-3-nitropyridin-2-amine (19.50 g, 117 mmol) was dissolved in 200 mL of ethanol at room temperature with suspended palladium on carbon 10% (1 g, 9.40 mmol). A solution of hydrazine (14.95 g, 467 mmol) in 50 mL of ethanol was added dropwise at room temperature, and reaction was stirred overnight. Filtering through Celite® pad and evaporation provided N2-ethylpyridine-2,3-diamine as a dark red solid (12 g, 75%).
