2-Bromo-1-(4-(dimethylamino)phenyl)ethanone → 3-[p-(Dimethylamino)phenacyl]-1-[[p-(dimethylamino)benzylidene]-amino]-2-ethylimidazolium bromide

Participants

Reaction Steps

A solution of 2.42 g (10 mmol) of 1-[[p-(dimethylamino)benzylidene]amino]-2-ethylimidazole is treated with 2.42 g (10 mmol) of p-dimethylaminophenacyl bromide. After stirring at 40° for 30 minutes the product is crystallized out by the addition of ether and recrystallized from methylene chloride/ether. There is obtained 3-[p-(dimethylamino)phenacyl]-1-[[p-(dimethylamino)benzylidene]-amino]-2-ethylimidazolium bromide of melting point 247°.
