| titleOfInvention | The method of obtaining β-lapachone |
| abstract | The subject of the application is a method for obtaining ß-lapachone, consisting in the cyclization of lapachol in an acid medium, and then isolating crude ß-lapachone from the reaction medium and its crystallization, characterized in that lapachol is subjected to a cyclization reaction in a methanesulfonic acid medium, and after After cyclization, the crude β-lapachone is isolated from the reaction mixture by cooling it and diluting it with water, after which the crude β-lapachone precipitate is crystallized from nitromethane and dried. |
