Reaction Steps

0.96 g of 3-(3,5-bis(trifluoromethyl)phenyl)-1-(3-chloro-4-methylphenyl)-4,4,4-trifluoro-3-hydroxybutan-1-one, 1.92 g of toluene, 0.48 g of thionyl chloride and 0.32 g of pyridine were fed, and stirred for 6 hours at 70° C. The mixture was cooled to room temperature, and separated by adding 10 ml of toluene and iced water. The organic phase was washed with water, and the solvent was distilled off under reduced pressure. The obtained residue was roughly purified by using a small amount of silica gel to obtain 0.92 g of 3-(3,5-bis(trifluoromethyl)phenyl)-1-(3-chloro-4-methylphenyl)-4,4,4-trifluoro-2-buten-1-one as yellow liquid.
