Versuchsvorschrift

5-Bromo-2-fluorobenzonitrile (0.370 g) was heated at 110° C. for 1 hour in concentrated sulfuric acid (10 ml). After cooling, the reaction was diluted with ice-cold water and the slurry was extracted into ethyl acetate, dried over anhydrous magnesium sulfate, filtered and evaporated to afford the sub-title compound as a solid (0.328 g).
