Versuchsvorschrift

A solution of 19.9 g (0.1 mol) of 1-benzylideneamino-2-ethyl-imidazole in 200 ml of 1.5N hydrochloric acid is subjected to a steam distillation until benzaldehyde no longer results. The mixture is evaporated and the product obtained is recrystallized from ethanol/ether. There are obtained 14.5 g of 1-amino-2-ethylimidazole hydrochloride of melting point 90°-91°.
