6-Methoxy-2-aminopyridine, as well as organic compounds, is synthesized by several methods.
One method is to use 2-chloro-6-methoxy pyridine as the starting material. This material is first mixed with ammonia and put into an autoclave. The temperature in the kettle is raised to an appropriate degree, such as 100-150 ° C, and the pressure is also adjusted to an appropriate degree, about 2-5 MPa. Under this condition, the chlorine atom is replaced by an amino group. After several times of reaction, 6-methoxy-2-aminopyridine can be obtained. The key to this reaction lies in the precise control of temperature and pressure. If the temperature is too high or the pressure is not appropriate, side reactions will occur, and the purity and yield of the product will be affected.
The second method starts from 2-hydroxy-6-methoxypyridine. First, react with a suitable reagent, such as p-toluenesulfonyl chloride, to convert the hydroxyl group into a p-toluenesulfonate ester group. This step is carried out in a mild alkaline environment, such as pyridine as a solvent and providing alkalinity. Then, the intermediate product is treated with sodium azide, and the sulfonate group is replaced by an azide group through a substitution reaction. Finally, the azido group is reduced with a reducing agent, such as lithium aluminum hydride, to obtain 6-methoxy-2-aminopyridine. Although this step is complicated, the reaction selectivity of each step is quite high, and the product purity is good.
There are also those who use 6-methoxypyridine-2-carboxylic acid as raw material. First, it is converted into the corresponding acid chloride, which can be treated with thionyl chloride or oxalyl chloride. The acid chloride is then reacted with ammonia to obtain an amide. 6-Methoxy-2-aminopyridine can be obtained by converting amide group into amino group after Hoffmann degradation reaction and treating with sodium hypobromite and other reagents. This approach is also a common synthesis method, but the reaction conditions need to be carefully controlled to obtain satisfactory results.
