1.9 g (5.8 mmol) of 1-amino-2-ethyl-3-(3,4,5-trimethoxybenzyl)imidazolium chloride are dissolved in 38 ml of glacial acetic acid, whereupon the solution is treated with 0.86 g (5.8 mmol) of p-dimethylaminobenzaldehyde, stirred at room temperature for 52 hours and then evaporated. The product is recrystallized from ethanol/ether. There is obtained 2-ethyl-1-[[p-(dimethylamino)benzylidene]amino]-3-(3,4,5-trimethyoxybenzyl)imidazolium chloride of melting point 211°.
