The synthesis of methyl 5- [ (4-bromo-2-chlorophenyl) amino] -4-fluoro-1-methyl-1H-benzimidazole-6-carboxylic acid esters is an important task in organic synthesis. The method is mostly based on the organic reaction mechanism and previous experience.
Take 4-bromo-2-chloroaniline first, which is one of the starting materials for the reaction. Mix it with suitable carboxylic acid derivatives, such as active esters of fluorinated benzimidazole-6-carboxylic acids or acid chlorides, etc., in a suitable organic solvent. Commonly used organic solvents, such as dichloromethane, N, N-dimethylformamide, etc., can fully dissolve the reactants without adverse interference to the reaction.
The reaction system needs to add an appropriate amount of alkali, such as triethylamine, potassium carbonate, etc. The function of alkali is to neutralize the acid generated by the reaction and promote the positive progress of the reaction. Control the reaction temperature, depending on the activity and reaction process of different reactants, or low temperature ice bath, or room temperature, or moderate heating, generally between 0 ° C and 100 ° C.
When reacting, the reaction process needs to be closely monitored. The reaction liquid spot plate can be taken regularly by thin layer chromatography, and the suitable development agent can be used to expand. The position and change of the spots can be observed under ultraviolet lamp to determine whether the reaction is complete.
After the reaction reaches the expected degree, post-treatment is carried out. First, the organic phase and the aqueous phase are extracted with water and organic solvent. The organic phase is dried with a desiccant such as anhydrous sodium sulfate to remove water. Then the organic solvent is removed by vacuum distillation to obtain a crude product.
The crude product is purified by column chromatography. Select a suitable silica gel column, elute with different proportions of eluent, collect the eluent containing the target product, and concentrate it again to obtain pure methyl 5- [ (4-bromo-2-chlorophenyl) amino] -4 -fluoro-1-methyl-1H-benzimidazole-6-carboxylate. The whole synthesis process requires fine operation and attention to the control of various reaction conditions to obtain satisfactory yield and purity.

This is a compound named methyl 5- [ (4-bromo-2-chlorophenyl) amino] -4-fluoro-1-methyl-1H-benzimidazole-6-carboxylic acid ester. Its physical properties are complex and have specific laws.
Looking at its morphology, it may be in a solid state at room temperature and pressure, because this class of compounds containing benzimidazole structure has a strong intermolecular force, resulting in a high melting point, and then exists in a solid state under normal conditions. However, its specific appearance may be crystalline or powdered, which is related to the synthesis process and crystallization conditions. If the crystallization rate during synthesis is slow, the conditions are mild, or the crystalline product is obtained, the appearance is regular and shiny; if the crystallization rate is fast and the conditions are changeable, it may be powdery.
In terms of solubility, the compound contains many hydrophobic groups, such as benzene rings, halogen atoms, etc., so the solubility in water is poor. Water is a polar solvent, and the polarity of this compound is relatively weak. According to the principle of "similar miscibility", it is difficult to dissolve in water. However, in organic solvents, the situation is different. Halogenated hydrocarbon organic solvents such as dichloromethane and chloroform may have a certain solubility in them because of their similarities in structure and the matching of intermolecular forces. If it is a polar organic solvent, such as methanol and ethanol, although its polarity is different from that of the compound, it can also dissolve part of the compound to a certain extent because it contains groups that can form hydrogen bonds with the compound.
Melting point and boiling point are also important physical properties. Due to the existence of a conjugated system and groups such as halogen atoms and methyl groups in the molecule, the intermolecular force is enhanced, resulting in a higher melting point. The conjugated system enhances the planarity of the molecule, increases the contact area between molecules, and increases the force; the halogen atom and methyl group affect the intermolecular force through induction effects. The specific melting point value may need to be accurately determined experimentally, but it can be inferred that it is higher than that of common low-molecular organic compounds. The boiling point is the same, higher intermolecular forces require more energy for gasification, and the boiling point is correspondingly higher.
In terms of density, due to the relatively large atomic mass of elements such as bromine and chlorine in the molecule, its unit volume mass increases, and the density may be greater than that of common organic solvents and water. However, the actual density is also affected by factors such as crystal structure, and the exact value needs to be measured experimentally.
In addition, the compound may have a certain stability, the structure of benzimidazole is relatively stable, and the substituents such as halogen atoms and methyl groups adjust the distribution of its electron cloud, without causing significant structural changes. However, under specific conditions, such as strong acid, strong alkali environment or high temperature, light, etc., or chemical reactions occur, the structure changes, and the physical properties also change.
