1.37 g of 1-(4-bromo-3-methylphenyl)-3-(3,5-dichlorophenyl)-4,4,4-trifluoro-3-hydroxybutan-1-one, 2.74 g of toluene and 0.89 g of thionyl chloride were fed, and the mixture was heated to 80° C. 0.48 g of pyridine was slowly added in dropwise, and the mixture was stirred for 90 minutes at 80° C. The mixture was cooled to room temperature, and separated by adding iced water. The organic phase was washed with a diluted aqueous solution of sodium hydroxide, and the solvent was distilled off under reduced pressure. 1.31 g of 1-(4-bromo-3-methylphenyl)-3-(3,5-dichlorophenyl)-4,4,4-trifluoro-2-buten-1-one was obtained as a yellow solid.
