실험 절차
A mixture of 1-(2,4-dichlorophenyl)-2-(4-methylimidazol-2-yl)ethan-1-one (0.33 M) and N,N-dimethylformamide-dimethyl acetal (DMFDMA) (25 ml) was stirred for 2.5 h at 70-75° C. The DMFDMA was then removed under reduced pressure and dried under high vacuum for several hours giving a light orange solid in quantitative yield. The enaminone product (2Z)-1-(2,4-dichlorophenyl)-3-(dimethylamino)-2-(4-methylimidazol-2-yl)prop-2-en-1-one was typically used without further purification.
