Abstract
Przedmiotem zgłoszenia jest nowa pochodna tiofenu, octan 4-(3-metylotiofen-2-ylo)-butan-2-olu o wzorze 1. Zgłoszenie obejmuje też sposób otrzymywania pochodnej tiofenu, octanu 4-(3-metylotiofen-2-ylo)-butan-2-olu o wzorze 1, który polega na tym, że 4-(3-metylotiofen-2-ylo)-butan-2-on poddaje się reakcji redukcji borowodorkiem sodu w środowisku metanolu, a otrzymany w tej reakcji 4-(3-metylotiofen-2-ylo)-butan-2-ol, po wyodrębnieniu ze środowiska reakcji, poddaje się reakcji estryfikacji bezwodnikiem octowym w obecności pirydyny w środowisku dichlorometanu, zaś produkt estryfikacji, po wyodrębnieniu ze środowiska reakcji, oczyszcza się chromatograficznie.The subject of the application is a new thiophene derivative 4- (3-methylthiophen-2-yl) -butan-2-ol acetate of formula 1. The application also includes a method for obtaining a thiophene derivative 4- (3-methylthiophen-2-yl) acetate - butan-2-ol of formula 1, which consists in the fact that 4- (3-methylthiophen-2-yl) -butan-2-one is subjected to a reduction reaction with sodium borohydride in a methanol medium, and the 4- (3) obtained in this reaction 3-methylthiophen-2-yl) -butan-2-ol, after isolation from the reaction medium, is subjected to esterification with acetic anhydride in the presence of pyridine in a dichloromethane medium, and the esterification product, after isolation from the reaction medium, is purified by chromatography.
