Versuchsvorschrift

Ethyl(benzylidene-amino)-(3,4-dichlorophenyl)acetate (425 g) was dissolved in methylene chloride (1.8 L). 10N Aqueous sodium hydroxide (1.2 L), allyl bromide (158 mL), and tetrabutylammonium sulfate (41 g) were added to the resultant solution, followed by stirring at room temperature for one hour. The reaction mixture was subjected to partitioning. Water (1 L) was added to the aqueous layer, and then the mixture was extracted with methylene chloride. The thus-obtained organic layer was washed with saturated brine, dried over sodium sulfate anhydrate, and concentrated under reduced pressure, to thereby give the title compound (518 g). The title compound was used in the next step without further purification.
