Procedure

3-Nitro-5-trifluoromethylbenzonitrile (1 g, 4.63 mmol) was dissolved in methanol (8 mL) and added activated charcoal (0.1 g), FeCl3.6H2O (17 mg, 0.06 mmol) and N,N-dimethylhydrazine (3.7 mL, 48.6 mmol). The mixture was refluxed overnight. The mixture was filtered and the volatiles removed in vacuo. The residue was purified by chromatography on silica using a mixture of heptane and ethyl acetate (4:1) as eluent affording 3-amino-5-trifluoromethylbenzonitrile.
