First, take appropriate fluoroaromatic hydrocarbons and methoxy nitrile derivatives, under specific basic conditions, in an organic solvent, catalyzed by a suitable catalyst, carry out nucleophilic substitution reaction. This process requires temperature control within a certain range, so that the reaction can occur smoothly and form a preliminary intermediate. Subsequently, the intermediate is cyclized in an acidic or alkaline environment to construct a quinoline ring system. Adjusting the acid-base strength, reaction time and temperature of the reaction can promote the inner ring of the molecule to obtain the precursor of the target product. Finally, the precursor is oxidized or other appropriate functional group conversion steps to achieve the synthesis of 7-fluoro-6-methoxy-4-oxo-1,4-dihydroquinoline-3-formonitrile.
Furthermore, quinoline derivatives can also be started. Select the appropriate quinoline parent and modify it at a specific position. The introduction of methoxy groups before the sixth position of the quinoline ring can be completed by halogenated quinoline and methoxylation reagents under metal catalysis. Then, an oxo-substituted group is introduced at the 4 position, which is achieved by oxidation or reaction with a carbonylating agent. As for the introduction of fluorine atoms at the 7 position, nucleophilic fluorination reagents can be used to replace the halogen atoms or other leavable groups at the corresponding positions under appropriate conditions. Finally, the methonitrile group is introduced at the 3 position, which can be achieved by nucleophilic substitution or other related reactions with the help of cyanide reagents, and the target product is obtained.
