Procedure
3.2 g of 5-chloro-3-(difluoromethyl)-1-methyl-1H-pyrazole-4-carboxylic acid and 44.3 ml of thionyl chloride were refluxed for 5 hours. After cooling down, the reaction mixture was evaporated under vacuum to yield 3.5 g of 5-chloro-3-(difluoromethyl)-1-methyl-1H-pyrazole-4-carbonyl chloride as a yellow oil.
