What are the synthesis methods of 2,4,7-TRIBROMOBENZO [D] THIAZOLE?
2% 2C4% 2C7 - TRIBROMOBENZO%5BD%5DTHIAZOLE is 2,4,7-tribromobenzo [d] thiazole, and the synthesis method is as follows:
The starting material is mostly a compound containing sulfur and benzene ring structure, such as 2-amino-4,7-dibromothiophenol. First, the raw material is reacted with a suitable acylating agent, such as acetyl chloride or benzoyl chloride, under alkali catalysis conditions, in an organic solvent such as dichloromethane or trichloromethane to form an amide intermediate. The base can be selected from triethylamine or pyridine, etc. This step requires slow dropwise acylating agent in a low temperature environment to ensure the controllability of the reaction and prevent side reactions from occurring.
Then, the above amide intermediates are transferred to a strong oxidant system. The commonly used oxidants are m-chloroperoxybenzoic acid (m-CPBA) or hydrogen peroxide in combination with a catalyst. The reaction solvent can be selected from dichloromethane or ethyl acetate, etc., and the reaction is reacted at room temperature or under appropriate heating conditions. The strong oxidant promotes the cyclization of the molecule to form a benzothiazole ring structure. This process requires close monitoring of the reaction process, which can be tracked by means of thin-layer chromatography (TLC) or high-performance liquid chromatography (HPLC).
Finally, the bromination reaction is carried out at a specific position on the benzothiazole ring. The bromination reagent is liquid bromine or N-bromosuccinimide (NBS). If liquid bromine is used, it needs to be slowly added to a suitable solvent such as carbon tetrachloride under low temperature and inert gas protection; if NBS is used, the reaction can be heated in a solvent such as chloroform in the presence of an initiator such as benzoyl peroxide. The synthesis of 2,4,7-tribromobenzo [d] thiazole is achieved by controlling the amount of brominating reagent and reaction time. After the reaction is completed, the product is separated and purified by means of extraction, washing, drying, column chromatography or recrystallization to obtain a high-purity target product.
