2-{1-(Methoxycarbonyl)ethoxy}-3-nitropyridine → 3-Amino-2-{1-(methoxycarbonyl)ethoxy}pyridine

Participants

Reaction Steps

A mixture of 1.7 g of 2-{1-(methoxycarbonyl)ethoxy}-3-nitropyridine, 102 mg of platinum oxide, and 7.5 ml of ethanol was stirred at room temperature under an atmosphere of hydrogen gas for 3.5 hours. The gas in the atmosphere on the reaction system was replaced with nitrogen gas, and the reaction mixture was filtered through Celite. The filtrate was concentrated. The residue was subjected to silica gel column chromatography to give 1.16 g of 3-amino-2-{1-(methoxycarbonyl)ethoxy}pyridine.
