Procedure

A mixture of 3 g of N-(2-fluoro-4-chloro-5-carboxyphenyl)-2,3-dimethylmaleic acid imide, 4.5 g of potassium carbonate, 1 ml of 1,3-dichloropropene and 50 ml of 2-butanone is heated under reflux for 16 hours. The precipitate is separated off and the filtrate is concentrated by evaporation. 3.3 g of N-[2-fluoro-5-(3-chlorallyloxycarbonyl)-4-chlorophenyl]-2,3-dimethylmaleic acid imide are obtained in the form of an oil. Refractive index nD24 1.5640.
