Reaction Steps

To a stirred solution of 657 g diethylaniline in 2 liter toluene is added dropwise over ca. 5 minutes 416 g methyl chloroformate. Then to the stirred mixture 500 g N-(3-methyl-2-butenyliden)-isopropylamine in 500 ml toluene is added dropwise over 2 hours, maintaining the temperature between 25° and 30° C. Stirring is continued for 1 hour upon completion of the addition and the reaction mixture is treated with 400 ml of water and 90 ml conc. hydrochloric acid.
