Reaction Steps

In 37 ml of toluene was dissolved 30 g (0.124 mole) of 2,4,5-trifluoro-3-difluoromethoxybenzoic acid, and 35 ml of thionyl chloride and 0.5 ml of N,N-dimethylformamide were added thereto. 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.
