(ii.c) 1.9 g 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 of p-dimethylaminobenzaldehyde and stirred at room temperature for 52 hours and the solution is evaporated. The product is recrystallized from ethanol/ether. There is obtained 2-ethyl-1-[[p-(dimethylamino)benzylidene)amino]-3-(3,4,5-trimethoxybenzyl)imidazolium chloride of melting point 211°.
