Procedure
A solution of 14.7 g of 2-fluoro-5-nitrobenzoic acid and 23.1 g of 2-furylmethylamine in 250 ml of ethanol is boiled under a reflux condenser for 6 hours. After the solvent has been removed by distillation under reduced pressure, the residue is dissolved in 150 ml of water, the pH is adjusted to approximately 2 with 2 N HCl, and the precipitate is filtered off. After the precipitate has been washed several times with water, it is dried in a stream of air. Pale yellow crystals, melting point 190°-192° C. (from isopropanol).
