Procedure

293 mg (1 mmol) of 3-amino-1-[[p-(dimethylamino)-benzylidene]amino]-2-ethylimidazolium chloride are dissolved in 40 ml of ethanol, whereupon the solution is hydrogenated at room temperature over 50 mg of palladium (5 percent on carbon). After crystallization from ethanol/ether there is obtained 3-amino-1-[[p-(dimethylamino)benzyl]amino]-2-ethylimidazolium chloride of melting point 153°-154°.
