4-Amino-5-methylpyridine-2 (1H) -one, that is, 4-amino-5-methylpyridine-2-one, has many synthesis methods, and the ancient method is now described in detail.
First, a nitrogen-containing heterocyclic compound is used as the starting material. Suitable pyridine derivatives can be found, and amino and methyl groups are introduced at specific positions. For example, a pyridine substrate is used to introduce methyl groups before its 5 position. In the past, a specific methylating agent was often used. Under appropriate reaction conditions, after many attempts, the methyl group was successfully connected to the 5 position. Then, the amino group was introduced at the 4 position. This step may require the help of ingenious reaction paths, such as traditional means such as diazotization, introducing suitable amination reagents, and finally obtaining the target product.
Second, it is based on the strategy of constructing a pyridine ring. Select a chain compound containing suitable functional groups, construct a pyridine ring through cyclization reaction, and introduce the required amino and methyl groups to the ring at the same time. First, a compound with a specific carbon chain structure and potential reaction check points is used to construct a pyridine ring through a series of reactions such as condensation and cyclization. During the construction process, the reaction sequence and conditions are cleverly designed, so that amino and A are successfully connected based on the desired 4 and 5 bits. This process requires detailed control of various reaction conditions, such as temperature, pH, catalyst, etc., in order to make the reaction proceed in the expected direction.
Third, other related heterocycles are also used as starting materials and obtained through structural modification. For example, a similar heterocycle is selected and its structure is converted into 4-amino-5-methylpyridine-2-one through gradual modification. Or the heterocycle is first reacted by ring opening and substitution, and the required functional groups are gradually introduced, and then closed-loop operations are used to construct pyridine rings and accurately locate amino and methyl groups. This path requires a deep understanding and grasp of the reactivity and transformation laws of heterocycles in order to make the synthesis path smooth.
