Versuchsvorschrift
In a 500-ml flask, place 100 ml of concentrated nitric acid (70%) and warm to 45° C. Add 30.6 g (0.2 m) of 5-fluoro-benzoxazol-2-one (1a; X=F) and stir at 50° C. for 3 hrs. Add 240 ml of water slowly, and stir and cool to room temperature. Collect solid, wash with water, and dry in air to give 35.0 g (88%) of 5-fluoro-6-nitro-benzoxazol-2-one (2a; X=F) as pale yellow solids.
