Procedure

First, 4.3 g (11 mmol) of N-(2,6-dichloro-4-trifluoromethylphenyl)-2,2,3,3,3-pentafluoropropionamide was dissolved in 22 ml of dichloromethane, to which 1.8 ml of carbon tetrachloride and 4.5 g (17 mmol) of triphenylphosphine were added at room temperature, and the mixture was stirred for 18 hours. The reaction mixture was concentrated under reduced pressure, followed by addition of hexane, and undissolved matter was removed by filtration, and the filtrate was concentrated under reduced pressure. The residue was subjected to silica gel column chromatography to give 3.8 g of N-(2,6-dichloro-4-trifluoromethylphenyl)-2,2,3,3,3-pentafluoropropionimidoyl chloride.
