실험 절차

A mixture of 4.53 g of 4-trifluoromethoxy-2-nitrophenol, 35 ml of ethyl acetate and 1.0 g of 5% palladium on carbon was stirred under about one atmosphere of hydrogen at room temperature for 1.7 hours. The mixture was filtered through Celite™. The filtrate was concentrated under reduced pressure to give 3.92 g of 2-amino-4-trifluoromethoxy phenol.
