Procedure

12.00 g 4-(Cyclohexylmethyl-amino)-3-nitro-benzoic acid methyl ester were dissolved in 75 ml ethyl acetate and 75 ml methanol, 0.45 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 and after precipitation with cyclohexane 12.00 g (93%) of 3-Amino-4-(cyclohexylmethyl-amino)-benzoic acid methyl ester were obtained.
