The synthesis methods of N-methylbenzothiazole-2-thione have existed in ancient times, and each method is exquisite. First, benzothiazole is used to react with methylation reagents, which is a common method. Benzothiazole has a stable structure, but it reacts when it encounters active methylation reagents, such as iodomethane and dimethyl sulfate. In suitable solvents, such as acetone and acetonitrile, a base is used as a catalyst. The base can be potassium carbonate, sodium carbonate, etc., and the two meet. Through the mechanism of nucleophilic substitution, the methyl group enters the position of benzothiazole, and then N-methylbenzothiazole-2-thione is obtained. At the time of reaction, it is necessary to control the temperature, observe the reaction process, and avoid side reactions.
Second, use 2-mercaptobenzothiazole as the starting material, first make it form a salt with the base, and then meet with the methylation reagent. The thiohydrogen group of 2-mercaptobenzothiazole is active, and it is easy to deproton when exposed to alkali and form a sulfur negative ion. This negative ion has strong nucleophilicity and attracts the methyl group of the methylation reagent to form a carbon-sulfur bond, and then obtain the target product. In this process, the strength, dosage, and type and ratio of methylation reagents are all key to the reaction.
Third, or synthesized by o-aminothiophenol with carbon disulfide and methylation reagent according to a specific reaction path. The condensation reaction between o-aminothiophenol and carbon disulfide first forms an intermediate product, and then encounters a methylation reagent. After a specific transformation, N-methylbenzothiazole-2-thione is obtained. This approach requires fine regulation of the reaction conditions at each step. The purity and yield of the product are all related to the properties of the solvent, the level of temperature, and the length of the reaction time.
