The method of preparing methyl 3 - (sulfamic acid) - 2 - thiophenecarboxylate is especially complicated and belongs to the field of organic synthesis. The commonly used methods include starting with 2 - thiophenecarboxylic acid, first by acylation to obtain 2 - thiophenecarboxylic chloride. Then with the alkali metal salt of the sulfamic acid, such as sodium sulfamate, in a suitable organic solvent, such as dichloromethane, under mild reaction conditions, or at room temperature, or slightly heated, stirring the reaction. The two are nucleophilic substitution, the sulfur atom nucleophilic attacks the carbonyl carbon of the acyl chloride, and the chlorine leaves to obtain the precursor of methyl 3 - (sulfamic acid) - 2 - thiophenecarboxylate. After the esterification step, catalyzed by methanol and strong acid, or concentrated sulfuric acid, or p-toluenesulfonic acid, heated and refluxed, the carboxyl group and methanol are formed into esters to obtain the target product.
There is another method, using 3-halo-2-thiophenecarboxylate as the starting material, and the halogen atom can be chlorine and bromine. The alkali metal salt of sulfamic acid and aminosulfonic acid can also be prepared by heating the reaction with the help of a phase transfer catalyst such as tetrabutylammonium bromide in a suitable solvent such as N, N-dimethylformamide, and the halogen atom is replaced by an aminosulfonyl group. These two types of methods have their own advantages and disadvantages. The former acylation step may require an anhydrous environment, and the operation is slightly complicated; the latter raw material 3-halo-2-thiophenecarboxylate may not be easy to obtain, but the steps are relatively simple. All require fine operation, and it is well selected according to the specific conditions and needs of the experiment.
