Reaction Steps

To a mixed solution of 4-amino-3-nitrobenzonitrile (8 g) in EtOH/THF (40 ml/40 ml) was added Pd—C (50% wet) (0.8 g), followed by stirring under an H2 atmosphere for 12 hours. The reaction solution was filtered through celite, and concentrated. The residue was powdered/washed with a mixed solvent of IPE and IPA, and collected by filtration to obtain 3,4-diaminobenzonitrile (6.3 g) as orange powders.
