One method, or follow the classical cyclization condensation path. First take the appropriate fluoroquinoline derivative, which needs to have a specific substituent to lay the foundation for the subsequent reaction. Mix it with a reagent containing amino cyclopropyl group in a suitable organic solvent. This organic solvent, when it has good solubility and stability, such as dichloromethane, N, N-dimethylformamide, etc. Then, add an appropriate amount of condensing agent, such as dicyclohexyl carbodiimide (DCC), etc., to promote the condensation reaction between the two. The reaction temperature needs to be carefully regulated. Initially, it can be initiated at a low temperature, and gradually heated to a moderate temperature to make the reaction proceed smoothly. After this step, it is expected to form a preliminary skeleton structure. The
secondary method may also start with the construction of oxazine rings. Select specific amino phenols, react with halogenated hydrocarbons with suitable substituents, and introduce key substituents. Then, the resulting product is reacted with cyclopropylamine derivatives under alkaline conditions. This alkaline condition can be created by alkaline substances such as sodium hydroxide and potassium carbonate. The strength and reaction time of alkalinity have a great influence on the reaction process and product purity. During the reaction process, stirring may be required to facilitate full contact of the reactants. After a series of reactions, the construction of the oxazine ring is realized, and the target product precursor is obtained.

Furthermore, there is still a strategy. First prepare active esters containing fluoroquinoline-6-carboxylic acids, such as those formed with p-nitrophenol. The active ester is reacted with a nucleophilic reagent of 1-aminocyclopropyl group, and the nucleophilic reagent attacks the carbonyl carbon of the active ester to achieve the introduction of the aminocyclopropyl group. After that, the oxazine ring structure is constructed through an intramolecular cyclization reaction. This cyclization reaction may require the participation of specific catalysts, such as Lewis acid. The type and dosage of catalysts need to be carefully considered in order to make the reaction efficient and obtain the desired product. Each method has its own advantages and disadvantages, and it needs to be weighed according to the actual situation.
