A solution of 2.42 g of 1-[[p-(dimethylamino)benzylidene]amino]-2-ethylimidazole is treated with 2.42 g 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°.
