The method of synthesizing N-tert-butyl-5-chlorothiophene-sulfonamide is quite delicate. The first step is often to use 5-chlorothiophene as the starting material. This thiophene compound is sulfonated to introduce the sulfonyl group into the thiophene ring at the appropriate position. When sulfonating, choose the appropriate sulfonating reagents, such as concentrated sulfuric acid and fuming sulfuric acid, and control the temperature, time and material ratio of the reaction, so that the reaction is smooth, to obtain 5-chlorothiophene sulfonic acid or its corresponding derivatives.
Next, the obtained 5-chlorothiophene sulfonic acid derivative is converted into sulfonyl chloride.

After the reaction of sulfinyl chloride, sulfur dioxide and hydrogen chloride gas are formed, which are easy to separate and are quite commonly used. The reaction is carried out in suitable solvents, such as dichloromethane, chloroform and other halogenated hydrocarbon solvents, which can promote the reaction to occur smoothly, and 5-chlorothiophene sulfonyl chloride is obtained.
The last step is to react 5-chlorothiophene sulfonyl chloride with tert-butylamine. Tert-butylamine is a nucleophilic reagent that attacks the carbonyl carbon of the sulfonyl chloride, and the chlorine leaves to form N-tert-butyl-5-chlorothiophene-sulfonamide. In this step, the appropriate acid binding agent can remove the generated hydrogen chloride, shift the balance to the right, and increase the yield.
