Summary: | The disclosure provides a method for the preparation of a diarylisoxazolé sulfonamide compound comprising contacting a deoxybenzoin with a secondary amine to form a diarylenamine compound; contacting the diarylenamine compound with an acetylating agent to form an acetyl diarylenamine compound; contacting the acetyl diarylenamine compound with a source of hydroxylamine to form an diaryl isoxazolol compound; eliminating water from the diaryl isoxazolol compound to form a diaryl isoxazole compound, chlorosulfonating the diarylisoxazole compound to form a chlorosulfonyl diaryl isoxazole compound; and contacting the chlorosulfonyl diaryl isoxazole compound with a source of ammonia to form the diarylisoxazole sulfonamide compound.
L'invention concerne un procédé destiné à la préparation d'un composé à base de diarylisoxazole sulfonamide, qui consiste à mettre en contact une désoxybenzoïne avec une amine secondaire pour former un composé de diarylenamine; à mettre en contact le composé de diarylenamine avec un agent d'acétylation pour former un composé d'acétyl de diarylenamine; à mettre en contact le composé d'acétyl de diarylenamine avec une source d'hydroxylamine pour former un composé de diaryle isoxazolole; à éliminer l'eau du composé de diaryle isoxazolole pour former un composé de diaryle isoxazolole; à chlorosulfonater le composé de diarylisoxazole pour former un composé de chlorosulfonyle diaryle isoxazole; et à mettre en contact le composé de chlorosulfonyle diaryle isoxazole avec une source d'ammoniac pour former un composé de diarylisoxazole sulfonamide. |
