Adding a certain compound to certain chemical reactions, such as: 139585-48-1, 2-Chloro-5-methoxypyridine, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound, name: 2-Chloro-5-methoxypyridine, blongs to pyridine-derivatives compound. name: 2-Chloro-5-methoxypyridine
5) 2-Hydrazino-5-methoxypyridine; A solution of the2-chloro-5-methoxypyridine (4.0 g) in hydrazine monohydrate (30 ml) was stirred at 100C for 24 hours. After cooling with air, the reaction solvent was evaporated under reduced pressure. To the residue was added chloroform and 1N aqueous sodium hydroxide and the phases were separated. The organic layer was dried over anhydrous magnesium sulfate. After filtration,_the solvent was evaporated under reduced pressure to give 2-hydrazino-5-methoxypyridine (705 mg, 18%) as an oily product. LC-MSm/z: 140 (M+H)+.
At the same time, in my other blogs, there are other synthetic methods of this type of compound,139585-48-1, 2-Chloro-5-methoxypyridine, and friends who are interested can also refer to it.
