実験手順

6.49 g of 4-bromo-3-(pentafluoroethyl)-1H-pyrazole-1-ylmethanol was dissolved to 60 ml of dichloromethane. 3.2 ml of thionyl chloride was added to the solution, followed by stirring at room temperature for overnight. The reaction mixture was concentrated under reduced pressure to obtain 6.84 g of 4-bromo-1-(chloromethyl)-3-(pentafluoroethyl)-1H-pyrazole.
