80 °C

To α-fluorocinnamic acid (5.48 g, 33 mM), thionyl chloride (40 ml) was added, and the thus obtained mixture was stirred at 80° C. under refluxing for 2 hours. After cooling it to a room temperature, the unreacted thionyl chloride was distilled off under reduced pressure to give a syrup-like α-fluorocinnamoyl chloride.
