Reaktionsschritte

A solution of 3-(3-nitro-phenyl)-acrylonitrile (500 mg, 2.87 mmol) in 5% aqueous AcOH (10 ml) was heated to 80° C. Iron powder (1.44 g, 25.8 mmol) was then added and the resulting mixture was stirred for 3 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) and 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.
