Reaction Steps
To a mixture of 4-Methoxy-3-nitropyridine (5.0 g, 32.44 mmole) in ethanol (100 mL) was added 10% palladium on carbon catalyst (200 mg). The resulting mixture was allowed to shake under a hydrogen atmosphere (50 psi) for 6 h. at room temperature. TLC (50% ethyl acetate/hexane) indicated complete consumption of starting material. Filtration through celite to remove the catalyst and concentration gave 3- Amino-4 methoxypyridine (4.0 g, 32.44 mmol, 100% yield) as dark red oil.
