Versuchsvorschrift

Formic acid (7 mL, 186 mmol) and acetic anhydride (140.1 mL, 150 mmol) were heated together at 55° C. for 2 hours. The mixture was cooled to room temperature, THF (11 mL) was added followed by 4-bromoaniline (10 g, 58 mmol) in THF (20 mL). The mixture was stirred at room temperature for 3 hours before evaporating to dryness. Trituration of the solid gave the subtitled compound as a light brown solid (8.22 g). MH− 198/200. 1H NMR δ (CDCl3) 6.93-7.04 (2H, d), 7.24 (2H, s), 8.59-8.70 (1H, d).
