Procedure

To a solution of 2,2'-bis(acetamido)- 5,5'-dinitrobiphenyl (34.1 g, 0.0953 mole) in concentrated sulfuric acid (500 ml) was added, slowly, 250 ml of water. The reaction mixture was stirred and heated at 110° C. and 1 mm Hg to give 24.9 g (96 %) of 2,2'-diamino- 5,5'-dinitrobiphenyl. An analytical sample, m.p. 315°-317° C., was obtained by recrystallization from ethanol-tetrahydrofuran.
