Procedure

1.49 g of 4-dimethylamino-benzaldehyde are added to a solution of 0.88 g of 1,3-diamino-2-isopropyl-imidazolium chloride in 15 ml of glacial acetic acid. After allowing the reaction mixture 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-isopropyl-imidazolium chloride of melting point 241°.
