What are the common synthesis methods of 5-iodine-2,4-dimethoxypyrimidine?
The common synthesis methods of 2,4-dimethoxybenzaldehyde are as follows:
First, m-xylene is used as the starting material. M-xylene is first chloromethylated, and chloromethyl is introduced under suitable catalysts and specific reaction conditions. After that, chloromethyl is reacted with urotropine to form a corresponding quaternary ammonium salt, and then acidic hydrolysis is performed to obtain 2,4-dimethoxybenzaldehyde. The raw materials for this method are relatively easy to obtain, and the steps are relatively conventional. However, the chloromethylation reaction conditions need to be carefully controlled, otherwise side reactions are easy to occur, affecting the yield and purity.
Second, p-cresol is used as the starting material. P-cresol is first methylated. Under specific reagents and conditions, methyl groups are introduced at the ortho-phenolic hydroxyl position to generate 2,4-dimethylphenol. Subsequently, 2,4-dimethylphenol is methoxylated and converted into 2,4-dimethoxybenzene using suitable methoxygenation reagents. Finally, the methyl group on the phenyl ring is oxidized to an aldehyde group through a mild oxidation reaction to obtain the target product. This path has relatively good reaction selectivity in each step, but some reagents are special and require higher reaction conditions.
Third, m-cresol is used as the starting material. M-cresol is methoxylated first to obtain m-methoxyphenol. Afterwards, in a suitable reaction system, m-methoxyphenol reacts with methylating reagents to introduce methyl at a specific position in the benzene ring to form 2,4-dimethoxyphenol. Finally, through a specific oxidation method, the phenolic hydroxyl ortho-methyl is oxidized to an aldehyde group to achieve the synthesis of 2,4-dimethoxybenzaldehyde. The reaction steps of this method are relatively compact, but the oxidation steps need to be precisely controlled to avoid excessive oxidation.
All synthesis methods have advantages and disadvantages. According to actual needs, considering the cost of raw materials, reaction conditions, yield purity and many other factors, the appropriate method should be carefully selected to achieve the purpose of synthesis.

What are the physical properties of 5-iodine-2,4-dimethoxypyrimidine?
2,4-Dimethoxypropane, its physical properties are as follows:
This substance is a colorless and transparent liquid at room temperature, with an ether-like odor. Its boiling point is in a specific range, generally about [X] ° C. This boiling point characteristic enables it to realize gas-liquid transformation under specific temperature conditions. In the distillation, separation and other operations of chemical production, it can be separated from other substances according to this boiling point difference.
Its melting point is relatively low, about [Y] ° C, indicating that it will solidify at lower temperatures, showing good low-temperature fluidity. This characteristic is of great significance in some application scenarios where the low-temperature state of substances is required.
2,4-dimethoxypropane has a density less than that of water, about [Z] g/cm ³, which makes it float on the water surface when mixed with water. This density difference can be exploited when operations such as liquid-liquid separation are involved.
It is slightly soluble in water, but it can be well miscible with common organic solvents such as ethanol, ether, acetone, etc. This solubility characteristic determines that it can be used as a solvent in organic synthesis, providing a homogeneous reaction environment for many organic reactions and helping the reaction to proceed more efficiently. At the same time, due to its limited solubility in water, it can better maintain the stability of the reaction environment in some reaction systems that need to avoid excessive contact with water.
In addition, the vapor pressure of 2,4-dimethoxypropane is at a specific value within a certain temperature range, which affects its existence in the gas phase and the volatilization rate. For open systems or scenarios involving gas-phase reactions, vapor pressure parameters have potential effects on the reaction process and product yield.
