실험 절차

0.45 g 4-(2-Ethyl-cyclohexylamino)-3-nitro-benzoic acid methyl ester were dissolved in 60 ml methanol, 0.02 g of palladium on carbon (10%) were added and the mixture was hydrogenated at 5 bar for 4 h. The catalyst was removed by filtration over celite, the filtrate was concentrated to obtain 0.40 g (100%) of 3-Amino-4-(2-ethyl-cyclohexylamino)-benzoic acid methyl ester.
