Procedure

65 ml of benzene was added to 10 grams of 3-(2-thienyl)acrylic acid. 7.8 ml of thionyl chloride was added dropwise slowly thereto at ambient temperature. The temperature was elevated to 70° 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.
