To prepare 3 - [ (E) -Phenyldiazenyl] Pyridine - 2,6 - Diamine Hydrochloride (1:1), the following ancient method can be used.
First take pyridine - 2,6 - diamine as the base material, which needs to be selected with high purity. Place it in a clean reactor, dissolve it with an appropriate amount of organic solvent, such as ethanol, dichloromethane, etc., stir to disperse uniformly.
Second prepare diazobenzene salt, starting with aniline, and obtain it by diazotization. Aniline is first dissolved in dilute acids such as hydrochloric acid, cooled to a low temperature, about 0-5 ° C. Slowly add an aqueous solution of sodium nitrite dropwise, during which the temperature and dropwise rate are strictly controlled to prevent side reactions.
When the diazobenzene salt is ready, slowly drop it into the solution containing pyridine-2,6-diamine. When adding dropwise, continue to stir and maintain a low temperature environment. This reaction is a process of nucleophilic substitution. The diazobenzene group will be combined with pyridine-2,6-diamine to obtain 3- [ (E) -Phenyldiazenyl] Pyridine-2,6-diamine.
After the reaction is completed, the reaction solution is post-treated. First, an appropriate alkali solution, such as sodium carbonate solution, neutralizes the excess acid. Then extract, extract the product with an organic solvent such as ethyl acetate, and leave the organic phase in the separation liquid. The organic phase is dried by anhydrous sodium sulfate, desiccant is removed, and then distilled under reduced pressure to remove the organic solvent to obtain the crude product.
The crude product is refined at the end, often by recrystallization. Select a suitable solvent, such as an ethanol-water mixed solvent, add heat to dissolve the crude product, filter out insoluble impurities while hot, cool the filtrate, and crystallize the product. Filter and dry to obtain a pure 3- [ (E) -Phenyldiazenyl] Pyridine-2,6-diamine.
To obtain 3- [ (E) -Phenyldiazenyl] Pyridine - 2,6 - Diamine Hydrochloride (1:1), dissolve the above product in an appropriate amount of organic solvent, slowly introduce hydrogen chloride gas, until the reaction is complete. After concentration, crystallization, filtration, drying and other steps, the final target product is obtained. The whole process requires strict operation, temperature control and time control to maintain the purity and yield of the product.
