Procedure

0.89 g (5 mmol) of 1,3-diamino-4-(hydroxymethyl)-2-methylimidazolium chloride and 1.49 g (10 mmol) of 4-dimethylaminobenzaldehyde are dissolved in 20 ml of glacial acetic acid. After 22 hours the precipitated product is filtered off and recrystallized from ethanol. There is obtained 1,3-bis[[p-(dimethylamino)benzylidene]amino]-4-(hydroxymethyl)-2-methylimidazolium chloride of melting point 237° (dec.).
