Versuchsvorschrift

14.4 g(0.053 mol) of N-(2-amino-5-nitrobenzoyl)-o-toluidine and 6.3 g(0.08 mol) of pyridine are dissolved in 300 ml of tetrahydrofuran. 12.2 g(0.126 mol) of fluoroacetyl chloride are added to the solution for 10 minutes under ice-cooling. The solution is stirred at the same temperature for 30 minutes and then at room temperature for 2.5 hours. The reaction solution is allowed to stand at room temperature overnight. The crystalline precipitate is collected by filtration, washed with water and then dried. 16.4 g of N-(2-fluoroacetamido-5-nitrobenzoyl)-o-toluidine are obtained.
