What is the synthesis method of 2-chloro-1-methylpyridin-1-ium 4-methylbenzenesulfonate?
To prepare 2-chloro-1-methylpyridine-1-onium + 4-methylbenzene sulfonate, the following ancient method can be used.
First take an appropriate amount of 2-chloropyridine and place it in a clean reactor. The kettle should be made of glass or ceramic to prevent corrosion. Then slowly add an appropriate amount of methylating agent, such as iodomethane or dimethyl sulfate, to the kettle. When adding, be careful not to splash the reagent. This process should be carried out at a mild temperature, about 30 to 50 degrees Celsius, which can be controlled by water bath or oil bath. The reaction takes about 2 to 4 hours (about 3-6 hours). This step aims to methylate the nitrogen atom of 2-chloropyridine and produce 2-chloro-1-methylpyridine-1-onium cation.
After the above reaction is completed, take another appropriate amount of 4-methylbenzenesulfonic acid and dissolve it in a suitable solvent, such as ethanol or acetone. The solvent should be pure and free to ensure a smooth reaction. Slowly drop the solution into a reactor containing 2-chloro-1-methylpyridine-1-onium cation. When adding dropwise, it is still necessary to stir continuously, and the temperature should be maintained near room temperature, not too high or too low. After the dropwise addition is completed, continue to stir for 1 to 2 hours (about 1.5-3 hours), so that the two can fully react to produce 2-chloro-1-methylpyridine-1-onium + 4-methylbenzene sulfonate.
After the reaction is completed, pour the reaction solution into the separation funnel and extract several times with a suitable organic solvent, such as dichloromethane or ethyl acetate. After extraction, collect the organic phase and dry it with anhydrous sodium sulfate to remove the moisture. Then, by reduced pressure distillation, remove the organic solvent to obtain a crude product.
To obtain a pure product, the crude product can be recrystallized in a suitable solvent, such as ethanol-water mixed solvent. When recrystallizing, the crude product is first dissolved in an appropriate amount of hot solvent, filtered hot to remove insoluble impurities. The filtrate is allowed to stand and cool, allowing the crystals to slowly precipitate out. After the crystals are completely precipitated, the crystals are collected by filtration with a Brinell funnel, washed with a small amount of cold solvent, and dried to obtain a pure 2-chloro-1-methylpyridine-1-onium + 4-methylbenzene sulfonate. The whole process requires careful operation, paying attention to factors such as temperature and reagent dosage, in order to make the reaction smooth and obtain the desired product.
