Procedure

1.49 g (10 mmol) of 4-dimethylamino-benzaldehyde are added to a solution of 0.88 g (5 mmol) of 1,3-diamino-2-propyl-imidazolium chloride in 15 ml of glacial acetic acid. After leaving to stand at room temperature for 2 days the product is crystallized out by the addition of ether and then recrystallized from ethanol. There is obtained 1,3-bis[[p-(dimethylamino)benzylidene]amino]-2-propyl-imidazolium chloride of melting point 252°.
