If manganese dioxide is oxidized, heat it in a suitable solvent, such as dichloromethane, and reflux it to make the reaction fully proceed. The hydroxymethyl group of 4-methyl-3- (hydroxymethyl) pyridine is oxidized to form an aldehyde group to obtain 4-methylpyridine-3-formaldehyde.
Second, it is prepared by substitution reaction of pyridine derivatives. Using 4-methylpyridine as the starting material, under suitable conditions, it is introduced into a suitable substituent at the 3rd position, and this substituent is converted into an aldehyde group by subsequent reactions. If a halogenated reagent is used first, under specific conditions, a halogen atom is introduced at the 3rd position of 4-methylpyridine to obtain 3-halo-4-methylpyridine. The halide is then reacted with magnesium metal to form a Grignard reagent, and then reacted with orthoformate. After hydrolysis, 4-methylpyridine-3-formaldehyde can be obtained.
Third, the coupling reaction catalyzed by transition metals is also a good method. Select a suitable pyridine-containing structural substrate and an aldehyde-containing precursor under the action of a transition metal catalyst such as a palladium catalyst. If a suitable halogenated pyridine derivative is reacted with an aldehyde-based reagent, in the presence of a palladium catalyst and a ligand, in a suitable reaction system, such as a basic environment, 4-methylpyridine-3-formaldehyde can also be obtained.
All methods have their own advantages and disadvantages, and it is necessary to choose carefully according to the actual situation, such as the availability of raw materials, the difficulty of reaction conditions, and the purity of the product, in order to achieve the purpose of synthesis.
