Reaction Steps

2-Methoxy-3-carbomethoxy-5-nitropyridine (850 mg, 4 mmol) was added to a medium pressure Parr shaker bottle (250 mL) containing 100 mg of 20% Pearlman's catalyst (palladium hydroxide/carbon) and 50 mL of methanol. The bottle was pressurized to 50 psi of hydrogen and shaken for 2 hours. By TLC, no starting material was observed (98/2 CH2Cl2 /MeOH). The catalyst was filtered off, the methanol was removed under reduced pressure and the product used in the next step without further purification. Recovered 680 mg of product (95% yield).
