The choice of starting materials is crucial. Often based on quinoline derivatives with specific substituents, this derivative needs to be carefully pretreated to activate its specific check point and facilitate subsequent reactions. < Br >
The first step is to make the quinoline derivative undergo nucleophilic substitution reaction with the fluorine-containing reagent in an appropriate solvent at a specific temperature and under the action of a catalyst, and introduce fluorine atoms. This step requires precise control of the reaction conditions. Due to the introduction position and number of fluorine atoms, it has a profound impact on the structure and properties of the product.

From the perspective, it may be a solid at room temperature, but the exact physical form still needs to be determined according to the actual situation. Its melting and boiling point, due to the existence of various chemical bonds and interactions in the molecule, causes complex intermolecular forces, so the melting and boiling point is high. The molecules contain atoms with high electronegativity such as fluorine, oxygen, and nitrogen, which make the molecules have a certain polarity, polarity or affect their solubility. In organic solvents, or due to the principle of similar miscibility, there is a certain solubility in some polar organic solvents, such as ethanol, acetone, etc.; in water, although the carboxyl group can form a hydrogen bond with water, the overall molecular structure may limit its water solubility, so the solubility in water may be limited.
From the theory of chemical properties, its carboxyl group is acidic and can neutralize with bases to form corresponding carboxylates. The lone pair of electrons on the nitrogen atom in the molecule makes it alkaline and can react with acids. In addition, the compound contains multiple unsaturated bonds and heterocyclic structures. These parts have high electron cloud density and nucleophilic properties, which can participate in nucleophilic substitution reactions, nucleophilic addition reactions, etc. The presence of cyclopropyl group, due to the ring tension, makes this part of the chemical activity is high, and it is prone to reactions such as ring opening.
