Methyl 2-(3-nitropyridin-2-yloxy)acetate → 3-Amino-2-(methoxycarbonyl)methoxypyridine

Participants

Reaction Steps

A mixture of 55.9 g of 2-(methoxycarbonyl)methoxy-3-nitropyridine, 8.64 g of 10% palladium/carbon and 600 ml of ethyl acetate was stirred for 2 hours at room temperature under hydrogen atmosphere. The reaction system was purged with nitrogen, then, the reaction solution was filtrated through Celite, and the filtrate was concentrated. The residue was subjected to silica gel column chromatography to obtain 46.76 g of 3-amino-2-(methoxycarbonyl)methoxypyridine. Intermediate Production Example 8
