実験手順

8.20 g of 5-nitro-1-naphthylamine (43.6 mmol) in 35 ml of toluene are placed in a 0.1 liter autoclave with 0.5 g of palladium on carbon (5%) and hydrogenated at 50° C. and 40 bar hydrogen pressure for 5 h, stirring. On completion of the reaction, the cooled autoclave is depressurised and the catalyst is filtered off. With a quantitative conversion, 6.72 g of 1,5-naphthalenediamine (42.5 mmol, 97.5%) are formed.
