反应详情

A mixture of 3.13 g of 2-hydroxy-3-nitro-5-trifluoromethylpyridine, 40 ml of methanol and 0.85 g of 5% palladium on carbon was stirred under about one atmosphere of hydrogen at room temperature for two hours. The reaction mixture was filtered through Celite™. The filtrate was concentrated under reduced pressure to give 2.66 g of 3-amino-2-hydroxy-5-trifluoromethylpyridine.
