Procedure
To 20 ml of toluene, 1.4 g of 2,5-difluoro-4-(2-propynyloxy)benzoic acid, 0.8 ml of thionyl chloride and 10 mg of DMF were added, and the mixture was heated at reflux for 2 hours. Then, the reaction mixture was concentrated under reduced pressure, and 1.5 g of 2,5-difluoro-4-(2-propynyloxy)benzoyl chloride was obtained.
