In addition, sulfamilic acid or its salts are required as reagents to provide sulfamilic acid groups.
During the reaction process, first, in a suitable solvent, such as N, N-dimethylformamide (DMF), dichloromethane, etc., 3-halothiophene-2-carboxylate is mixed with a base. The function of the base is to activate the substrate, making it easier to react with nucleophiles. Commonly used bases include potassium carbonate, sodium carbonate, etc. Then, slowly add sulfamic acid or its salts. The reaction temperature and time need to be precisely controlled. Generally speaking, the temperature is controlled between room temperature and 80 ° C, and the reaction time varies from a few hours to more than ten hours, depending on the substrate activity and reaction scale. During the
reaction, sulfamate ions act as nucleophiles to attack the check point of the halogen atom of 3-halothiophene-2-carboxylic acid ester. After the nucleophilic substitution reaction, the halogen atom leaves to form the target product, methyl 3- (aminosulfonyl) thiophene-2-carboxylic acid ester.
After the reaction, the product needs to be separated and purified. Column chromatography is often used to select silica gel as the fixed phase, and a suitable eluent, such as a mixed solvent of petroleum ether and ethyl acetate, is used to separate according to the polarity of the product. Recrystallization can also be used to select a suitable solvent, so that the product is dissolved and then slowly crystallized to obtain a pure product. A higher purity methyl 3 - (sulfamyl) thiophene - 2 - carboxylate can be obtained by these steps.

Methyl 3- (aminosulfonyl) thiophene-2 -carboxylic acid ester This material requires careful attention when storing and transporting.
First talk about storage, the first environment is dry. Because of its certain hygroscopicity, if the environment is humid, it is easy to cause moisture and deterioration, which affects its quality and stability. The warehouse should choose a high and dry place to prevent rainwater from pouring back. Temperature is also the key, and it should be controlled in a cool area, generally not exceeding 25 ° C. Excessive temperature may cause chemical reactions, causing decomposition or changes in its properties. And it should be stored separately from oxidants, acids, bases and other substances. Because of its active chemical properties, contact with the above substances or react violently, resulting in accidents.
As for transportation, the packaging must be solid and reliable. Special containers are required to ensure a good seal and prevent leakage. During transportation, avoid severe bumps and collisions to prevent package damage. At the same time, transport vehicles should be well ventilated to reduce the risk of explosion due to the accumulation of volatile gases. Transport personnel should also be professionally trained and familiar with the characteristics of the substance and emergency treatment methods. In case of leakage, the scene should be quickly isolated, evacuated personnel, and properly handled according to relevant operating procedures. Do not panic.
