First, a specific aryl halide can be started. First, take an appropriate amount of aryl halide, place it in a clean reaction vessel, add a suitable base and catalyst, use a specific organic solvent as the medium, and make it undergo a nucleophilic substitution reaction at a precisely regulated temperature and time to generate key intermediates. After a multi-step reaction, cyclization, oxidation and other steps are completed in sequence, and the reaction conditions of each step are carefully adjusted, such as temperature, proportion of reactants, reaction time, etc., to achieve the desired product. In this process, the intermediate products of each step of the reaction need to be carefully separated and purified. Column chromatography, recrystallization and other methods are commonly used to ensure the purity of the product, and then 7-fluoro-6-methoxy-4-oxo-1,4-dihydro-3-quinoline formonitrile is obtained.
Second, it is also a good method to use fluorobenzaldehyde as a raw material. Under suitable basic conditions, fluorobenzaldehyde and nitrile compounds with specific activities are induced to condensate in an organic solvent to form a preliminary product. Subsequently, through ingenious intramolecular cyclization, catalyzed by a specific catalyst, the reaction temperature and time are precisely regulated, and the molecular structure is rearranged and cyclized, and the quinoline ring structure of the target compound is gradually constructed. Subsequent steps modify the substituents on the ring, such as the introduction of methoxy groups, etc., through multiple reactions, separation and purification operations, the desired product is finally obtained.
Third, the coupling reaction strategy catalyzed by transition metals is used. Select suitable halogenated aromatics and alkenyl nitriles, add appropriate ligands under the action of transition metal catalysts such as palladium and copper, and in suitable bases and organic solvents, a coupling reaction occurs to form important intermediates. After further cyclization, oxidation and functionalization, the reaction parameters are strictly controlled to make the reaction proceed in the direction of the target product. After each step of the reaction, the product needs to be carefully treated to ensure the quality and purity of the product, and finally 7-fluoro-6-methoxy-4-oxo-1,4-dihydro-3-quinolinocarbonitrile is obtained.
All of the above methods require the experimenter to have exquisite skills and rich experience, and to carefully control the reaction conditions in order to achieve efficient and high-purity synthesis. Each method has its own advantages and disadvantages, and it is necessary to carefully choose according to the specific experimental conditions and needs.
