Procedure
14 g of 3-fluoro-4-nitrophenol and 24 ml of aniline were mixed and stirred for 3 hours at 140° C. After cooling, it was dissolved in ethyl acetate and extracted six times with 2N aqueous hydrochloric acid. The organic phase was washed with saturated sodium chloride solution, dried on sodium sulfate, concentrated by evaporation in a vacuum, and the residue was crystallized from diisopropyl ether. 20.8 g was obtained.
