However, in terms of solubility, the compound may have a certain solubility in organic solvents such as dichloromethane, chloroform, N, N-dimethylformamide (DMF). Due to the structural characteristics of organic matter, it can be dissolved with organic solvents through intermolecular forces such as van der Waals force and hydrogen bonding.
As for its appearance, or white to light yellow solid powder, this speculation is derived from many pyridine derivatives with similar structures, which often exhibit such appearance characteristics.
Furthermore, its density is also difficult to describe accurately due to the lack of accurate data. However, according to the general laws of organic compounds, the density may be similar to that of common organic solids. Its volatile properties, or due to the presence of chlorine atoms, formyl groups and methoxy groups in the molecular structure, make it less volatile. This is because these groups enhance the intermolecular forces, making it more difficult for molecules to escape from the solid surface.

First, mix 2-methoxy-3-chloropyridine and DMF in a certain proportion. In a low temperature environment, slowly add POCl < unk >, add it dropwise, gradually heat up to a moderate temperature, and maintain the reaction for a period of time. After the reaction is completed, the target product can be obtained after proper post-processing, such as neutralization, extraction, column chromatography, etc.
Another route is to use the corresponding pyridine derivative as the substrate, first introduce the methoxy group, then introduce the chlorine atom at the appropriate position, and finally construct the formyl group through the appropriate reaction. In this route, when introducing the methoxy group, a strong base and a methoxy-containing reagent can be selected to react in a suitable solvent. When introducing the chlorine atom, a specific chlorination reagent and reaction conditions need to be selected according to the characteristics of the substrate. There are also various reaction options for the construction of the formyl group, such as variants of the Vilsmeier-Haack reaction, or other specific formylation methods. The reaction conditions of each step need to be carefully adjusted to achieve high yield and purity. The post-processing process should also be handled carefully to ensure the quality of the product.
