To prepare N- (1,5-dimethyl-3-oxo-2-furyl-2,3-dihydro-1H-pyrrole-4-yl) -4-bromobenzamide, the following ancient method can be used.
Take an appropriate 1,5-dimethyl-3-oxo-2-furyl-2,3-dihydro-1H-pyrrole-4-amine and place it in a clean reactor. Measure an appropriate amount of halogenating reagents, such as hydrobromic acid or brominating agent, and slowly add them to the kettle. Control the reaction temperature to a suitable range, either warm or cool, depending on the needs of the specific reaction, and stir at the same time to make the reactants fully mixed. The purpose of this step is to brominate the amine group to obtain a bromine-containing intermediate.
Take another 4-bromobenzoic acid, and place it in another reaction vessel with an appropriate condensation agent, such as carbodiimide condensation agent, and add an appropriate amount of organic solvent to dissolve the two evenly. Then pour the bromine-containing intermediate carefully into the mixture, raise the temperature, and maintain the reaction for a period of time. During this period, pay close attention to the reaction process, which can be monitored by thin-layer chromatography or other suitable analytical methods. This condensation reaction aims to connect the bromine-containing intermediate with 4-bromobenzoic acid to form N- (1,5-dimethyl-3-oxo-2-furyl-2,3-dihydro-1H-pyrrole-4-yl) -4-bromobenzamide.
After the reaction is completed, the reaction mixture is cooled to room temperature. Then, according to the nature of the product and the impurities, separate and purify. Or by extraction, the product is extracted with a suitable organic solvent to separate the impurities; or by column chromatography, the appropriate stationary phase and mobile phase are selected to separate the product from the impurities. Finally, through concentration, crystallization and other operations, pure N- (1,5-dimethyl-3-oxo-2-furyl-2,3-dihydro-1H-pyrrole-4-yl) -4-bromobenzamide can be obtained. The whole process needs to be handled with caution and attention should be paid to the control of reaction conditions to obtain satisfactory yield and purity.

N- (1,5-dimethyl-3-oxo-2-benzyl-2,3-dihydro-1H-indole-4-yl) -4-fluorobenzamide, which is an organic compound. Its physical properties are quite important and are related to many practical applications.
Looking at its appearance, it is often white to light yellow crystalline powder at room temperature and pressure. This color and morphology are easy to identify and process in experiments and production scenarios. Its melting point is in a specific range, generally speaking, about [X] ° C. The determination of the melting point is of great significance for the identification of purity. The higher the purity, the closer the melting point is to the theoretical value.
Solubility is also a key property. In organic solvents, such as dichloromethane, N, N-dimethylformamide, it exhibits good solubility, which is conducive to acting as a reactant or product in organic synthesis reactions, and is convenient for the construction, separation and purification of reaction systems. However, the solubility in water is very small, which is closely related to the large proportion of hydrophobic groups in its molecular structure.
The density of this compound is about [X] g/cm ³, and the density value is indispensable in the material measurement and equipment design involved in chemical production. In addition, its stability is good under normal conditions, but when exposed to strong oxidizing agents, strong acids or strong bases, the structure may change and chemical reactions may occur. Therefore, care must be taken to avoid contact with such substances during storage and use.
The combination of these physical properties lays the foundation for the application of N- (1,5-dimethyl-3-oxo-2-benzyl-2,3-dihydro-1H-indole-4-yl) -4-fluorobenzamide in organic synthesis, drug research and development, etc. Scientists and producers can rationally design reaction paths, optimize production processes, and plan storage and transportation methods according to their properties.
