Versuchsvorschrift

A solution of 3,5-bis(trifluoromethyl)aniline (1.28 g, 5 mmol, Aldrich) in acetic anhydride (5 mL) was stirred at room temperature for 12 h, then all of the solvent was removed to give 1.479 g (98%) of 1-acetamido-3,5-bis(trifluoromethyl)benzene as white needles. 1H NMR (CDCl3): δ2.229 (s, 3H); 7.589 (s, 1H); 8.048 (s, 2H).
