Abstract

Przedmiotem zgłoszenia jest oksym 7,4'-dietoksynaringeniny o wzorze 2 oraz sposób jej otrzymywania. Sposób ten polega na tym, że do substratu, którym jest 7,4'-dietoksynaringenina 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 7,4'-diethoxynaringenin oxime of formula 2 and the method of its preparation. This method consists in adding hydroxylamine hydrochloride and anhydrous sodium acetate in a molar ratio of at least 1: 1.5: 1.5 and a minimum amount of alcohol to the substrate, which is 7,4'-diethoxynaringenin of formula 1 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 continuous stirring, after which the mixture is poured into ice water, the precipitate is filtered under reduced pressure, and then the obtained crude product is purified.
