4-(Dimethylamino)Benzaldehyde → HCID 178437690, compound

Participants

Reaction Steps

1.18 g (7.9 mmol) of p-dimethylaminobenzaldehyde are added to a solution of 2.7 g (7.9 mmol) of 1-amino-2-ethyl-3-(p-methoxyphenacyl)-2-ethylimidazolium bromide in 40 ml of glacial acetic acid. The mixture is stirred at room temperature for 4 days, the product is crystallized out by the addition of ether and filtered off. It is washed with water, dried at room temperature and recrystallized from ethanol. There is obtained 1-[[p-(dimethylamino)benzylidene]amino]-2-ethyl-3-(p-methoxyphenacyl)-imidazolium bromide of melting point 244°-246°.
