実験手順

11.9 g of cyano-phenol and 32.6 g of diethyl-2-(4'-fluoro-phenoxy)-propionyl-malonate are dissolved in 150 ml of dimethyl sulfoxide, whereupon 13.8 g of potassium carbonate are added and the reaction mixture is stirred at 60° C. for 6 hours. The reaction mixture is filtered and the filtrate is evaporated. Thus 36 g of the desired compound are obtained, yield 86%.
