Reaction Steps
A solution of 55 g of 3-cyano-2,4,5-trifluoro-benzoyl chloride in 50 ml of toluene is added dropwise to a solution of 36.5 g of ethyl 3-dimethylamino-acrylate and 26.5 g of triethylamine in 140 ml of toluene at a temperature between 50 and 55° C. After stirring at 50° C. for 2 hours the reaction mixture is concentrated in vacuo. The crude product is used for the next step without further purification.
