Reaction Steps
A suspension of 2-(3-nitrophenyl)pyrazine (500 mg) in tetrahydrofuran (5 ml) and ethanol (5 ml) was hydrogenated over palladium on carbon (10% w/w, 50% wet, 200 mg) under hydrogen atmosphere for 6 hours. The catalyst was filtered off and the filtrate was evaporated. The residue was crystallized from dichloromethanediisopropyl ether to give 3-(pyrazin-2-yl)aniline (410 mg, 96.5%).
