Reaction Conditions

Reaction Steps

5.0 g (32 mmol) of 2-fluoro-5-nitroaniline were admixed with 10 ml (110 mmol) of acetic anhydride and 0.1 ml of conc. sulfuric acid and stirred at 100° C. for 1.5 hours. The solution was added to 100 ml of ice/water, and the precipitate which formed was filtered off and washed with water. The crude product was purified by chromatography (1:1 ethyl acetate/heptane) on silica gel (yield 5.4 g, 85%).
