Versuchsvorschrift

Ethyl(benzylidene-amino)-(3,4-dichlorophenyl)-acetate (1.41 mol) was dissolved in ethyl acetate (2.3 L). Allyl bromide (341 g), potassium carbonate (390 g), and tetrabutylammonium bromide (45 g) were added to the resultant mixture, followed by refluxing for 2.5 hours. The reaction mixture was left to cool to room temperature. The mixture was sequentially washed with water and saturated brine, dried over sodium sulfate anhydrate, and concentrated under reduced pressure, to thereby give the title compound (500 g, 94%).
