| titleOfInvention | A kind of preparation method of C2 substituted 2H-benzothiazole acylation derivative |
| abstract | The invention discloses a preparation method of C2-substituted 2H -benzothiazole acylated derivatives. The preparation method is as follows: mixing 2H -benzothiazole and substituted toluene, adding an oxidant K 2 S 2 O 8 , reacting in an air atmosphere, monitoring by TLC until the reaction is completed, and separating and purifying the reaction solution to obtain C2-substituted 2H -benzothiazole acylated derivatives. The present invention adopts the above-mentioned technology, uses K 2 S 2 O 8 as an oxidant, and a new method for synthesizing C2-substituted 2H -benzothiazole acylated derivatives through heating reaction in an air atmosphere, the method has a simple catalytic system and yields products. The yield is good and the substrate range is wide, which is suitable for popularization and application. |
