الإجراء التجريبي

A solution of 0,7 g (3,3 mmol) 1-amino-5-cyano-2-nitronaphthalene in a mixture of 75 ml ethanol and 75 ml ethyl acetate was hydrogenated at atm. pressure by using ca. 1 g Ra-Ni as a catalyst. The reaction mixture was filtered and evaporated in vacuo to give 1,2-diamino-5-cyanonaphthalene as yellow crystals. IR (KBr): 2220 cm-1 (nitrile function).
