Participants

Reaction Steps

After adding 5.34 g of toluene to 1.78 g (4.12 mmol) of 1-(6-(1H-1,2,4-triazol-1-yl)pyridin-3-yl)-3-(3,5-dichlorophenyl)-4,4,4-trifluoro-3-hydroxybutan-1-one, 0.98 g (8.25 mmol) of thionyl chloride and 0.65 g (8.25 mmol) of pyridine were added at 80° C., and stirred for 3 hours. The reaction solution was cooled to room temperature, and separated by adding 20 ml of ethyl acetate and 10 ml of water. After washing the ethyl acetate phase with an aqueous solution of 0.33 g of sodium hydroxide dissolved into 10 ml of water, the phase was washed with water. The solvent was distilled off under reduced pressure to obtain 1.69 g of 1-(6-(1H-1,2,4-triazol-1-yl)pyridin-3-yl)-3-(3,5-dichlorophenyl)-4,4,4-trifluoro-2-buten-1-one (yield 99.4%).
