3-Nitrophenylacetonitrile → (3-Amino-phenyl)-acetonitrile

A solution of 3-nitrophenyl acetonitrile (500 mg, 3.1 mmol) in 5% AcOH (10 ml) was heated to 80° C. Iron powder (1.5 g, 27 mmol) was then added and the resulting mixture stirred for 2 h. The reaction mixture was filtered through celite and the filter cake washed with MeCN (4×50 ml). The combined MeCN layers were evaporated in vacuo and the residue was re-dissolved in EtOAc (30 ml) followed by 2M HCl (30 ml). The aqueous layer was separated, basified to pH 10 with 6M NaOH, and extracted with EtOAc (3×80 ml). The combined organic layers were dried (MgSO4), filtered and the solvent removed in vacuo to give the title compound.
