Procedure

25.8 g (92 mmol) of potassium 3-cyano-3-(3,4-dichlorophenyl)acrylate were dissolved in 200 ml of 88% strength formic acid and admixed dropwise with 15 ml of concentrated sulfuric acid. The mixed was then heated under reflux for 3 h, poured at 90° C. into 2.5 l of water and stirred for 1 h, and the product was filtered off, washed with water and dried. Yield: 18.9 g, m.p. 112° C.
