Abstract

L'invention a pour objet un nouveau procédé de préparation de la 5,6-diamino-uracile à partir de la 5-nitroso-6-amino-uracile. Selon ce procédé on hydrogène catalytiquement le groupe nitroso de Ia 5-nitroso-6-amino-uracile en utilisant, comme milieu réactionnel, une base minérale. La 5,6-diamino-uracile est ainsi obtenue avec une pureté et un rendement élevés.
