The synthesis method of 7-bromobenzo [d] thiazole-2-thiol, although the ancient book "Tiangong Kaiwu" does not contain this specific method of synthesis, the process ideas contained in it may be useful for reference.
To synthesize 7-bromobenzo [d] thiazole-2-thiol, a common method is to use 2-amino-3-bromothiophenol as the starting material. First, it reacts with carbon disulfide under basic conditions. Bases such as sodium hydroxide or potassium hydroxide are combined at a suitable temperature of about 30 to 50 degrees Celsius. After nucleophilic addition, the sulfur atom of carbon disulfide is connected to the amino nitrogen atom to obtain an intermediate product.
Next, the intermediate product is interacted with methylating agents such as iodomethane or dimethyl sulfate to undergo a methylation reaction under mild conditions, about 20 to 30 degrees Celsius, so that the specific group of the intermediate product is substituted with methyl, and then cyclized to form a benzothiazole ring, resulting in 7-bromobenzo [d] thiazole-2-thiol.
Another method is to start with o-bromoaniline, first react with thiocyanates, such as potassium thiocyanate, in a suitable solvent, such as ethanol, and heat to 50 to 70 degrees Celsius to obtain o-bromophenylthiourea. Then it is co-heated with concentrated sulfuric acid at about 120 to 150 degrees Celsius. After a series of reactions such as cyclization and dehydration, the target product 7-bromobenzo [d] thiazole-2-thiol can also be obtained.
These two methods have their own advantages and disadvantages. The first step is slightly complicated, but the reaction conditions are milder; the last step is simple, but higher temperature and strong acidic conditions are required. In practical application, when considering factors such as raw material availability, cost and equipment conditions, the choice is made.
