実験手順

40.8 g of 1-chloro-2,4-dinitrobenzene, 2 g of Raney nickel (60%, aqueous), 1.5 g of formamidine acetate and 120 ml of methanol are introduced in an autoclave equipped with gas introduction stirrer. The air in the autoclave is then displaced by nitrogen and then by hydrogen. The hydrogenation is carried out at a pressure of 10 bar and a temperature of 60° C. The hydrogenation time is 11/4 hours. 1-Chloro-2,4-diaminobenzene, 99% pure (analysed as 1-Chloro-2,4-acetamidobenzene by liquid chromatography), is obtained in quantitative yield.
