Procedure
3.2 g of 5-chloro-3-(difluoromethyl)-1-methyl-1H-pyrazole-4-carboxylic acid and 44.3 mL of thionyl chloride were heated under reflux for 5 h. After cooling, the reaction mixture was concentrated under reduced pressure, giving 3.5 g of 5-chloro-3-(difluoromethyl)-1-methyl-1H-pyrazole-4-carbonyl chloride as a yellow oil.
