실험 절차

A mixture of 3-(2,4-dichlorophenoxy)-2-butanone (4.66 g) and N,N-dimethylformamide dimethylacetal (2.38 g) was heated under argon in an oil bath at 120° C. for 11 hours. The methanol produced in the reaction was removed under reduced pressure and the residue was triturated with n-hexane. The solid was collected by filtration and washed with cold diethyl ether to give 4-(2,4-dichlorophenoxy)-1-(dimethylamino)-1-penten-3-one. Yield 4.07 g.
