Versuchsvorschrift
To a suspension of 6.2 g (0.017 mol) of 3-[3,4-bis(acetyloxy)benzoyl]-2-oxo-1-imidazolidinecarboxamide in 50 ml of a 1:1 mixture of ethanol/water was added dropwise 2.1 ml of ammonia. After stirring for 10 minutes, a clear solution formed from which 3-(3,4-dihydroxybenzoyl)-2-oxo-1-imidazolidinecarboxamide began to crystallize after 15 minutes, yielding 3.8 g.
