Versuchsvorschrift

m-Nitroacetophenone (20 g) was dissolved in acetic acid (150 mL) under argon. Pyridinium tribromide (38.7 g) was added at once; the reaction was allowed to stir at room temperature for 1 hour and then quenched with water (250 mL). The product was filtered and air dried to give the title compound (25 g, 84%).
