Versuchsvorschrift
The base is liberated from 7.3 g (26 mmol) of 1-[[p-(dimethylamino)benzylidene]amino]-2-ethylimidazole hydrochloride with saturated sodium hydrogen carbonate solution. This base is taken up in methylene chloride. The solution is dried over sodium sulphate and concentrated. There is obtained 1-[[p-(dimethylamino)benzylidene]amino]-2-ethylimidazole of melting point 120°-121°.
