Synthesis

6393-40-4

17626-40-3

The general procedure for the synthesis of 3,4-diaminobenzonitrile from 4-amino-3-nitrobenzonitrile was as follows: palladium/carbon catalyst (500 mg, 10% purity) was added to a stirring solution of 4-amino-3-nitrobenzonitrile (2.00 g, 12.3 mmol) in methanol (20 mL). Subsequently, the reaction flask was degassed and filled with hydrogen (using a hydrogen balloon). The reaction mixture was stirred vigorously for 18 hours at 25°C. Upon completion of the reaction, the mixture was degassed under vacuum and backfilled with nitrogen, and this process was repeated three times. Afterwards, the reaction mixture was filtered through a diatomaceous earth pad and the filtrate was concentrated under vacuum to give 3,4-diaminobenzonitrile (1.47 g, 11.04 mmol, 90% yield) as a green oil, which was used directly in the next step of the reaction.
