The synthesis method of 6-methyl-2- (4-methylphenyl) imidazolo [1,2-a] pyridine has been around for a long time, and is described in detail below.
First, the nitrogen-containing heterocyclic compound and aromatic halogen are used as starting materials. First, the nitrogen-containing heterocyclic ring is mixed with a specific solvent and mixed with a base to form an active intermediate. This solvent is often selected as an aprotic solvent, such as N, N-dimethylformamide, because it has good solubility to both the reaction substrate and the base. The base is mostly potassium carbonate and the like, which is moderately basic and can effectively promote the reaction. After the active intermediate is formed, 4-methylphenyl halide is added. This halide has high activity and can rapidly undergo nucleophilic substitution reaction with intermediates. After careful temperature control and stirring, the crude product of the target product can be obtained. After column chromatography separation, recrystallization and other purification methods, the pure 6-methyl-2 - (4-methylphenyl) imidazolo [1,2 - a] pyridine can be obtained.
Second, the aldehyde, amine and pyridine derivatives are used as raw materials. First, the aldehyde and amine are condensed under the catalysis of acid to form Schiff base. The acid is often p-toluenesulfonic acid, which has good catalytic activity and has little effect on the reaction system. After the Schiff base is formed, it reacts with pyridine derivatives under specific conditions. This reaction requires high temperature and specific catalyst participation. The catalyst can choose transition metal complexes, such as palladium complexes. Palladium complexes can effectively promote the formation of carbon-nitrogen bonds in the reaction. After the reaction, the impurities are removed by extraction, washing, drying and other steps, and then by reduced pressure distillation, crystallization and other means to obtain the final product.
Third, based on imidazo [1,2-a] pyridine derivatives, methylation and arylation are carried out. First, imidazo [1,2-a] pyridine derivatives are reacted with methylation reagents to introduce methyl groups. Methylation reagents are mostly iodomethane or dimethyl sulfate, and the activity of the two is suitable and the reaction conditions are mild. After the methylation is completed, it is reacted with 4-methylphenylation reagent to introduce 4-methylphenyl. In this process, the control of reaction conditions is particularly critical, and the temperature, reaction time and reagent dosage will all affect the yield and purity of the product. After the reaction is completed, the high purity 6-methyl-2 - (4-methylphenyl) imidazolo [1,2-a] pyridine can be obtained by regular separation and purification steps.

6-Methyl-2 - (4-methylphenyl) imidazolo [1,2-a] pyridine, this is an organic compound. However, its price in the market is difficult to determine. Its price is often influenced by various factors, such as the cost of materials, the difficulty of preparation, the supply and demand of the market, and even the pricing strategy of merchants.
Looking at the past "Tiangong Kaiwu", the price of all things changes with the world. If the preparation of this compound is scarce and difficult to find, or the preparation method is complicated and diverse, it requires a huge amount of manpower and material resources, and its price is high. And if there are many people in the market, there will be few supply, which will also cause the price to remain high.
On the contrary, if the materials are abundant, the preparation method is simple, and the market demand is average, the price may be relatively easy. Today in the market, there may be merchants selling them with different purity and specifications, and the price varies accordingly. Or in the fine chemical raw material market, find relevant quotations, but they fluctuate very frequently, and it is difficult to give an exact price. Therefore, to know the details, it is necessary to visit various chemical material suppliers before they can get their recent prices.
