Reaction Steps

A solution of 2-amino-5-fluorobenzotrifluoride (2.025 g, 11.31 mmol, Aldrich) in acetic anhydride (10 mL) was stirred at room temperature for 12 h, and then most of the acetic anhydride was removed. The white needle crystals were collected by filtration, affording 2.445 g (98%) of 2-acetamido-5-fluorobenzotrifluoride. 1H NMR (CDCl3): δ2.205 (s, 3H); 7.229-7.335 (m, 3H); 8.055 (dd, 1H, J1 =4.8 Hz, J2 =8.4 Hz).
