Procedure
2-Fluoro-5-nitroaniline (30 g) was added portionwise over 45 minutes to a refluxing solution of 60 ml isoamyl nitrite in 225 ml benzene. After heating for a further 30 minutes at reflux, the mixture was cooled and the solvent removed by evaporation in vacuo. The residue was triturated many times with hot petroleum ether and the combined extracts were evaporated to give the product as a red oil (19.9 g, yield 49%). This material was used without further purification. NMR (CDCl3, 60MHz): 8.0-8.4 (m, 3H), 7.1-7.6 (m, 5H).
