Abstract

Przedmiotem wynalazku jest analog flawanonu, o nazwie chemicznej (E)-1-(2fenylochroman-4-ylideno)- tiosemikarbazyd, o wzorze przedstawionym poniżej. Zgłoszenie obejmuje tez sposób otrzymywania tego związku, który polega na reakcji flawanonu z tiosemikarbazydem w środowisku bezwodnego etanolu w obecności stężonego kwasu siarkowego (VI) w temperaturze 60°C w czasie 24 godzin, po czym mieszaninę reakcyjną z wytrąconym osadem pozostawia się do wystudzenia, a następnie wytrącony osad produktu sączy się pod próżnią i przemywa etanolem oraz destylowaną wodą.The present invention relates to a flavanone analog having the chemical name (E) -1- (2-phenylchroman-4-ylidene) -thiosemicarbazide having the formula shown below. The application also covers the method of obtaining this compound, which consists in reacting flavanone with thiosemicarbazide in anhydrous ethanol in the presence of concentrated sulfuric acid (VI) at a temperature of 60 ° C for 24 hours, then the reaction mixture with a precipitate is left to cool down, and then the precipitated product is filtered under vacuum and washed with ethanol and distilled water.
