Procedure

100 ml of benzene was added to 18.3 grams of p-chlorocinnamic acid. 12 ml of thionyl chloride was added dropwise slowly thereto at ambient temperature. The temperature was elevated to 80° C. and the heating was continued until foaming ceased. Benzene and thionyl chloride were distilled off and the residue was dried thoroughly under reduced pressure.
