Abstract

μέθοδος παρασκευής του 6-(5-νιτρο-2-φουρυλο) αζαουρακιλίου, ήτις περιλαμβάνει τα στάδια σχηματισμού του 6 (2-φουρυλο) αζαουρακιλίου δι' υποβολής της2-φουρουλο-φορμυλο-σεμικαρβαζόνης είς κατεργασίανμε ένα αλκαλικόν παράγοντα κλεισιματος του δακτυλίου εντο ενός αδρανους μέσου κα ιυπό την επίδρασινθερμότητος πρός μετατροπήν της ρηθείσης σεμικαρβαζόνης είς κυκλικής ένωσιν, και υποβολής του ούτω σχηματισθέντος 6-(2-φουρυλο) αζαουρακιλίου είς την ενέργειαν ενός μίγματος νιτρώσεως περιλαμβάνοντοςνιτρικόν οξύ, συνεπεία του οποίου το ρηθέν 6-(2-φουρυλο) αζαουρακίλιον μετατρέπεται είς το 6-(5-νιτρο-2-φουρυλο) αζαουρακίλιον. Process for the preparation of 6- (5-nitro-2-furyl) azauracil, comprising the steps of forming 6 (2-furyl) azauracil by subjecting 2-furuloformyl-semicarbazone to treatment with an alkaline blocking agent. medium under the effect of heating to convert said semicarbazone to a cyclic compound, and subjecting the thus formed 6- (2-furyl) azuracil to the action of a nitration mixture in 6- (5-nitro-2-furyl) azauracil.
