Procedure

67 ml of benzene was added to 10 grams of 3-(3-pyridyl)-acrylic acid. 8.1 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.
