80 °C

A mixture of 4.8 ml of thionyl chloride and 8.10 g of (-)-2-(pentafluorophenyl)propionic acid obtained in Example 4 was stirred for 10 hours at 80° C. Excess thionyl chloride was distilled off under reduced pressure, and the subsequent distillation under reduced pressure gave 6.61 g of (-)-2-(pentafluorophenyl)propionyl chloride having the aforementioned physical properties.
