Versuchsvorschrift
Phenylformimino benzyl thioether hydrochloride (28.5gm) was refluxed in chloroform (200 ml) with ethyl aminocyanoacetate (17.0gm) for 1 hour. On standing for 8 hours the addition of dry diethyl ether (250 ml) caused the precipitation of the 5-amino-4-carbethoxy-2-phenylimidazole hydrochloride (24.5gm) m.p. 228° C after recrystallisation from ethanol.
