The synthesis method of (4,5-methyl-2-mercaptobenzimidazole), although the ancient book "Tiangong Kaiwu" does not directly describe the synthesis of this substance, it can be deduced from many chemical synthesis principles contained in the book.
Synthesize this substance in the past, or take a suitable benzimidazole matrix first, choose a suitable reaction vessel, use copper salt or other metal salts as catalysts, add an appropriate amount of methylation reagents, such as iodomethane or dimethyl sulfate. At a certain temperature and reaction time, the methyl group is successfully connected to the 4th and 5th positions of benzimidazole. During the reaction, careful temperature control is required. If the temperature is too high, side reactions will occur, and if it is too low, the reaction will be slow.
After methylation is completed, a sulfhydryl group is introduced. Sodium hydrosulfide or thiourea and other sulfur-containing reagents are often used in alkaline environments, such as sodium hydroxide or potassium hydroxide solutions, through ingenious reactions, the sulfhydryl group is successfully connected to the 2 positions of benzimidazole. In this process, the control of the pH of the solution is crucial, and the alkalinity is too strong or too weak, which affects the effectiveness of the mercapylation reaction.
In addition, it is also used as the starting material of o-phenylenediamine and carbon disulfide to first condensate to form benzimidazole-2-thione intermediates, and then methylation is carried out to achieve methylation at the 4th and 5th positions. This approach also requires careful study of the reaction conditions of each step, such as the choice of reaction solvent and the proportion of reactants, etc., in order to make the synthesis reaction smooth and obtain the target product (4,5-methyl-2-mercaptobenzimidazole).

(4,5) -Methyl-2-mercaptobenzimidazole is an important chemical substance, and there are several precautions to be kept in mind during use.
First, safety protection must be comprehensive. This substance may be harmful to the human body. When exposed, wear appropriate protective equipment, such as gloves, protective glasses and protective clothing, to avoid direct contact with the skin and eyes. If inadvertently exposed, rinse with plenty of water immediately and seek medical attention according to the specific situation.
