Abstract

Przedmiotem zgłoszenia jest oksym 7-pentoksynaringeniny o wzorze 2 i sposób otrzymywania tego związku. Sposób polega na tym, że do substratu, którym jest 7-pentoksynaringenina 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 20 do 30 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-pentoxynaringenin oxime of formula 2 and the method of obtaining this compound. The 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-pentoxynaringenin of the formula (I), which is the reaction mixture protected from light and left at a temperature of 45 ° C to 55 ° C for 20-30 hours with continuous stirring, after which the mixture is poured into ice water, the precipitate is filtered under reduced pressure, and then the crude obtained the product is purified.
