Reaction Steps

To a suspension of charcoal (283 mg) in 25 ml of methanol was added iron (III) chloride hexahydrate (35 mg), and 2′-fluoro-6-hydroxy-5-nitrobiphenyl-3-carbonitrile (668 mg). The resultant green mixture was heated under nitrogen at 70° C. for 10 min. Hydrazine (403 μl) was added slowly, and the mixture was stirred for 2 h at 70° C. The mixture was then cooled to room temperature and filtered through a plug of Celite. The eluent was concentrated in vacuo to provide the title compound (543 mg, 92%). Mass spectrum (ESI) 229.1 (M+1).
