The method of preparing M-aminobenzoic acid ethyl methanesulfonate requires several steps. First, the esterification reaction is carried out with M-aminobenzoic acid and ethanol as materials, and an appropriate amount of sulfuric acid as a catalyst. At a suitable temperature and duration, the two combine to obtain M-aminobenzoic acid ethyl ester.
The specific operation is to take an appropriate amount of M-aminobenzoic acid and put it in a flask, slowly add ethanol, the amount of sulfuric acid is about the percentage of the total amount of reactants, stir well. Heat in an oil bath or a water bath, control the temperature between 60 and 80 degrees Celsius, and stir during the reaction period to promote its full reaction.
After the esterification reaction is completed, the step of separation and purification can be carried out. By distillation, the excess ethanol is removed first, and then the sulfuric acid is neutralized in alkali solution, and then extracted with an organic solvent. The organic phase is obtained. After drying with anhydrous sodium sulfate, it is distilled under reduced pressure to obtain pure M-aminobenzoate.
Second, the obtained M-aminobenzoate ethyl ester is reacted with methanesulfonic acid to obtain M-aminobenzoate methanesulfonate. In this step, dissolve M-aminobenzoate ethyl ester into an appropriate amount of organic solvent, such as dichloromethane or ethyl ether, and slowly add methanesulfonic acid dropwise under stirring. The speed of dropwise addition should be slow to avoid overreaction. After adding it dropwise, continue to stir at room temperature for a few times to make the two fully react.
After the reaction is completed, the crude product can be obtained by evaporating the solvent. Then purify by recrystallization, use a suitable solvent, such as ethanol-water mixed solvent, heat to dissolve the crude product, filter while hot, the filtrate is cooled and crystallized, and then filtered and dried to obtain high-purity M-aminobenzoate ethyl methanesulfonate. Throughout the preparation process, it is necessary to strictly control the reaction conditions and operation details to obtain high-quality products.
