The synthesis method of 1-methyl-1H-benzimidazole-2-ethylthioamide can be carried out according to the following steps.
The first benzimidazole is taken as the starting material, and its structure has a unique benzo five-element nitrogen-containing heterocycle, which is the core skeleton of the reaction. Mix benzimidazole with appropriate methylation reagents, such as iodomethane or dimethyl sulfate. In a suitable alkaline environment, basic substances can be selected from potassium carbonate, sodium carbonate, etc. Under these conditions, a nucleophilic substitution reaction occurs, and the nitrogen atom of benzimidazole acts as a nucleophilic check point to attack the methyl of the methylation reagent to generate 1-methylbenzimidazole. The key to this step is to precisely control the reaction temperature and time. If the temperature is too high, it is prone to side reactions.
