Participants

Reaction Steps

100 g of 4-amino-3-nitrobenzonitrile are suspended in 500 ml of 2-methoxyethanol. Gaseous hydrochloric acid is introduced, the temperature of the solution is allowed to rise to 70° C. in the course of the introduction, and the solution is maintained at this temperature by cooling until it decreases by itself. Finally, the solution is cooled to 0°-5° C., saturated with gaseous hydrochloric acid and allowed to stand overnight. The precipitate is then filtered off with suction, washed with isopropanol and dried over KOH in a desiccator.
