Versuchsvorschrift

2 ml (19 mM) of 2-Chloronitrobenzene and 2.7 ml (36 mM) of 2,2-difluoroethyl amine in 2 ml of acetonitrile were refluxed under stirring for 24 h. Water was added and the aqueous layer was extracted with ethyl acetate. The organic layer was washed with water and dried over anhydrous sodium sulfate. The solvent was removed under vacuum to give 3.65 g of N-(2,2-difluoroethyl)-2-nitroaniline as an orange solid. Yield: 95%.
