Abstract

Przedmiotem zgłoszenia jest oksym 7-etoksynaringeniny o wzorze 2. Zgłoszenie obejmuje też sposób otrzymywania tego związku, który polega na tym, że do substratu, którym jest 7-etoksynaringenina o wzorze 1 dodaje się chlorowodorek hydroksyloaminy oraz bezwodny octan sodu w stosunku molowym co najmniej 1:1,5:1,5 oraz minimalną ilość alkoholu, co stanowi mieszaninę reakcyjną, którą zabezpiecza się przed dostępem światła i pozostawia w temperaturze od 45°C do 55°C na okres od 24 do 72 godzin przy ciągłym mieszaniu, po czym mieszaninę wylewa się do wody z lodem, wytrącony osad sączy się pod zmniejszonym ciśnieniem, a następnie otrzymany surowy produkt oczyszcza się.The subject of the application is 7-ethoxynaringenin oxime of formula 2. The application also includes a method for obtaining this compound, which consists in adding hydroxylamine hydrochloride and anhydrous sodium acetate in a molar ratio of at least 1 to the substrate which is 7-ethoxynaringenin of formula 1 : 1.5: 1.5 and a minimum amount of alcohol, which is the reaction mixture, which is protected from light and left at a temperature of 45 ° C to 55 ° C for 24 to 72 hours with constant stirring, after which the mixture poured into ice water, the precipitate is filtered under reduced pressure, and then the crude product obtained is purified.
