Procedure
Formic acid (3 g) was added dropwise to acetic anhydride (5.4 g) which had been cooled to 0° C. The mixture was stirred at 0° C. for 15 minutes and then heated to 55° C. for 2 hours. The mixture was cooled to ambient temperature. THF (5 ml) and a solution of 2-fluoroaniline (2.22 g) in THF (15 ml) were added and the mixture was stirred at ambient temperature for 2 hours. The mixture was evaporated to give 2'-fluoroformanilide (2.8 g) which was used without further purification.
