5-bromo-2-nitroaniline is converted into 5-bromo-2-nitrobenzonitrile by treating the aniline derivative with sodium nitrite and hydrochloric acid and reacting the resulting diazonium salt with cuprous cyanide as in Example 2. The nitro group is reduced with stannous chloride and hydrochloric acid to give 4-bromo-2-cyanoaniline.
