Reaction Steps

To 36.0 g (0.15 mole) of 2,4,5-trifluoro-3-difluoromethoxybenzoic acid were added 45 ml of toluene, 15 ml of thionyl chloride and 0.2 ml of N,N-dimethylformamide, and the mixture was refluxed by heating for 4 hours. After the reaction, toluene and excess thionyl chloride were removed under reduced pressure to obtain 2,4,5-trifluoro-3-difluoromethoxybenzoyl chloride.
