3.24 g (12.6 mmol) of methyl 2-acetyl-3-(2-chloro-4-fluorophenyl)acrylate from Example VII are stirred with 1.74 g (12.6 mmol) of 3-methylene-1,3-thiazolidin-3-ium chloride [prepared in analogy to H. Mohrle et al., Z. Naturforsch. 42, 1035–1046 (1987)] in 50 ml of acetonitrile at 40° C. for 48 hours. After concentration, the residue is taken up in ethyl acetate and washed with water. The organic phase is dried over sodium sulfate and concentrated, and the residue is chromatographed on silica gel with cyclohexane/ethyl acetate (5:1→2:1) as mobile phase.
