What are Benzothiazole-2-thiol synthesis methods?

There are several common methods for synthesizing benzothiazole-2-thiol.

One is to use o-aminothiophenol and carbon disulfide as raw materials. In a suitable reaction vessel, mix o-aminothiophenol and carbon disulfide in a certain proportion, and add an appropriate amount of basic catalyst, such as potassium hydroxide or sodium hydroxide. Under heating conditions, the two undergo a condensation reaction. During the reaction, the temperature needs to be carefully controlled, usually maintained at a certain range, such as 60-80 degrees Celsius. In this reaction process, the carbonyl group of carbon disulfide interacts with the amino group and mercapto group of o-aminothiophenol gradually, and after complex changes, the final benzothiazole-2-thiol is obtained. After the reaction is completed, the product is purified by conventional separation methods, such as extraction, distillation, etc.

Second, o-halogenated aniline and thiocyanate are used as starting materials. First, the o-halogenated aniline and thiocyanate are placed in a solvent, such as ethanol or acetone. Add a catalyst, such as a copper salt catalyst. Under heating and stirring conditions, the halogen atom reacts with thiocyanate to form an intermediate of o-thiocyanidine. Subsequently, the intermediate is further cyclized in an acidic or basic environment and converted to benzothiazole-2-thiol. During this process, the choice of solvent, the amount of catalyst, and the reaction temperature and time all have a significant impact on the reaction yield and product purity.

Third, react with sodium hydrosulfide with 2-halobenzothiazole. Put 2-halobenzothiazole into the reaction system and add sodium hydrosulfide solution. At appropriate temperature and pressure, the halogen atom is replaced by hydrogen sulfide to obtain benzothiazole-2-thiol. This method is relatively direct, but the acquisition of 2-halobenzothiazole raw materials may be difficult, and the reaction conditions need to be carefully regulated to achieve the desired reaction effect.
