For example, specific thiophenol compounds and benzene ring derivatives are catalyzed by acids or bases to form benzothiophene rings through condensation and cyclization. In this process, the type and dosage of catalysts, and the pH of the reaction system are all key factors affecting the reaction. After the benzothiophene ring is formed, a methyl group and a cyanyl group are introduced as described above to obtain 3-methyl-1-benzothiophene-2-formonitrile.
Third, there are also those who use halogenated benzothiophene as raw material. First, the halogenated benzothiophene is reacted with a methylating reagent to replace the halogen atom with a methyl group. This reaction requires the selection of a methylating reagent with suitable activity and suitable reaction conditions to avoid the occurrence of side reactions. Subsequently, the cyanide group is substituted with a cyanide group to replace the halogen atom or other leavable groups to obtain the target product. In this process, precise control of reaction conditions, such as temperature, pressure, and reaction time, are all necessary conditions for obtaining high-purity products.
All these synthesis methods have their own advantages and disadvantages, and they need to be carefully selected according to actual needs and conditions to achieve the best synthesis effect.
