To prepare 3,4-diamino-2-methoxypyridine, the method is as follows:
First take a suitable starting material, usually a compound containing a pyridine ring as the group, because it has the mother core structure of pyridine, which can save the step of constructing a pyridine ring. If 2-methoxypyridine is used as the starting material, it can be nitrified first. In an appropriate reaction vessel, add an appropriate amount of 2-methoxypyridine, and then slowly add mixed acid (a mixture of sulfuric acid and nitric acid) dropwise to control the reaction temperature. If the temperature is too high, it is easy to cause side reactions such as polynitro substitution. The ratio of mixed acid, reaction temperature and time need to be precisely controlled, so that the nitro can be mainly replaced in the 3 and 4 positions of the pyridine ring. After the reaction is completed, 3,4-dinitro-2-methoxypyridine is obtained by separation and purification methods, such as extraction, column chromatography, etc.
Then, 3,4-dinitro-2-methoxypyridine is reduced to convert the nitro group into an amino group. The commonly used method is catalytic hydrogenation, adding 3,4-dinitro-2-methoxypyridine and an appropriate amount of catalyst (such as palladium carbon, etc.) to the reactor, and introducing hydrogen to control the reaction pressure and temperature. Chemical reduction methods can also be used, such as iron powder, hydrochloric acid, etc. as reducing agents. Iron powder reacts with hydrochloric acid to generate new hydrogen and reduce nitro groups to amino groups. After the reaction, through neutralization, filtration, concentration and other operations, 3,4-diamino-2-methoxypyridine crude products can be obtained, and then further purified by recrystallization and other means to obtain pure 3,4-diamino-2-methoxypyridine.
During the preparation process, each step of the reaction needs to be strictly controlled to improve the yield and purity, and the operation should follow safety specifications to prevent the occurrence of danger.
