Reaction Steps
To 17 ml of toluene were added 1.8 g of 3,5-difluoro-4-(2-propynyloxy)benzoic acid, 1 ml of thionyl chloride and 10 mg of DMF and the mixture was heated under reflux for 4 hours. Then, the reaction mixture was concentrated under reduced pressure to obtain 1.9 g of 3,5-difluoro-4-(2-propynyloxy)benzoyl chloride represented by the formula:
