Participants

Reaction Steps

To a solution of 1,6 g (5,9 mmol) 1-amino-5-bromo-2-nitronaphthalene in 50 ml dimethylformamide was added 1,1 g (11,8 mmol) cuprous cyanide. The reaction mixture was refluxed for 5 h, and then poured into a solution of 2,5 ml ethylenediamine in 80 ml water. Stirring was continued for 15 min., and then the precipitate was filtered off and washed with water and boiling ethyl acetate to give 1,0 g (80%) 1-amino-5-cyano-2-nitronaphthalene, m.p. 260-262° C. IR (KBr): 2200 cm-1 (nitrile function).
