4-{3-chloro-4-[(cyclopropylcarbamoyl)amino]phenoxy}-7-methoxyquinoline-6-carboxamide

This is a chemical nomenclature, and in order to know its chemical structure, it is necessary to analyze it according to the nomenclature. "4 - {3-chloro-4- [ (cyclopropanoformyl) amino] phenoxy} -7 -methoxyquinoline-6-formamide", which is composed of many parts.
"Quinoline" is the basic parent nucleus and has a nitrogen-containing heterocyclic structure. "7-methoxy" indicates that there is a methoxy group (-OCH 🥰) at the 7th position of the quinoline parent nucleus; "6-formamide", that is, there is a formamide group (-CONH ²) at the 6th position.
Look at the phenoxy part again, "3-chloro-4- [ (cyclopropanoyl) amino] phenoxy", indicating that the benzene ring has a chlorine atom (-Cl) at position 3, and a (cyclopropanoyl) amino group at position 4. Cyclopropanoyl, which is connected to a formyl group (-CO-), this formyl group is connected to the amino group and then connected to the benzene ring at position 4, and the phenoxy group is connected to the quinoline parent nucleus at position 4 as a whole.

To prepare 4 - {3-chloro-4- [ (cyclopropanoyl) amino] phenoxy} -7-methoxyquinoline-6-formamide, there are three methods.
One is to react 3-chloro-4-aminophenol with cyclopropanoyl chloride to obtain 3-chloro-4- [ (cyclopropanoyl) amino] phenol, and then react with 4,7-dichloro-7-methoxyquinoline-6-formamide under alkali catalysis to obtain the target by condensation. The raw materials are easy to obtain in this way, but the reaction conditions need to be precisely controlled. The amount of alkali, reaction temperature and time are all critical, and the yield will be affected if there is a slight difference in the pool.
The second is to prepare 4,7-dichloro-7-methoxyquinoline-6-formamide first, react with 3-chloro-4-hydroxyaniline to obtain an intermediate product, and then react with cyclopropanoyl chloride. This diameter step is slightly complicated, but the reaction of each step is relatively mild, which requires slightly less equipment. However, the separation and purification of intermediate products requires fine operation, otherwise impurities will affect the purity of the final product.
The third is to start with 7-methoxy-6-quinolinecarboxylic acid, and first form acyl chloride, which reacts with 3-chloro-4- [ (cyclopropionyl) amino] aniline. This way, the starting material is single and the process is short, but the price of 7-methoxy-6-quinolinecarboxylic acid may be higher, and the acyl chloride forming step requires an anhydrous environment, which requires strict reaction equipment and operation. If there is a little carelessness, there will be many side reactions.
All synthesis methods have their own advantages and disadvantages. The actual selection needs to comprehensively consider factors such as raw material cost, equipment conditions, product purity and yield, and weigh the advantages and disadvantages to choose the best method.

4- {3-Chloro-4- [ (cyclopropionyl) amino] phenoxy} -7-methoxyquinoline-6-formamide, this is an organic compound. Its physical properties are quite important, and it is related to its performance in various chemical processes and practical applications.
First of all, the appearance is usually white to white crystalline powder. This form makes the compound easy to handle and operate in many scenarios, and its powder shape is convenient for accurate weighing and mixing.
Melting point is also one of the key physical properties. After experimental determination, its melting point is in a specific temperature range, which is of great significance for the determination of the purity of the compound. If the purity is high, the melting point range is relatively narrow and stable; if it contains impurities, the melting point will shift and the range will become wider. This property is helpful for quality control and purity analysis.
In terms of solubility, the compound has a certain solubility in organic solvents such as dichloromethane, N, N-dimethylformamide. In dichloromethane, it can form a homogeneous solution, which is conducive to serving as a reaction medium in organic synthesis reactions, allowing the reactants to be fully contacted and accelerating the reaction rate. However, the solubility in water is very small, and this difference determines its separation, purification and application scenarios.
In terms of stability, under conventional environmental conditions, the compound is relatively stable. However, when exposed to strong acids, strong bases or high temperatures, the structure may change. If in a strong acid environment, its amide bonds may be hydrolyzed, which affects its chemical properties and functions. Therefore, it is necessary to avoid acid and alkali and control temperature during storage to maintain its stability and integrity.
4- {3-chloro-4- [ (cyclopropylformyl) amino] phenoxy} -7 -methoxyquinoline-6-formamide The physical properties of the amide are of important guiding value for its production, storage and application in the fields of organic synthesis and drug research and development.
