Ethyl 2- (ethylsulfanyl) -6,7-difluoro-4-hydroxy-3-quinolinecarboxylate is an organic compound, and its synthesis methods are rich and diverse. The following are the common ones:
First, fluorobenzene derivatives are used as starting materials. First, fluorobenzene derivatives are substituted with appropriate nucleophiles, such as thioalkyl compounds, to introduce ethyl thioalkyl groups. Subsequently, a series of reactions, such as condensation and cyclization, are performed to construct the quinoline ring structure.

Although the reaction steps are complicated, the reaction conditions of each step are relatively common in the field of organic synthesis and easy to control.
Second, quinoline derivatives are used as the starting materials. To modify the existing quinoline skeleton, fluorine atoms are introduced at a specific position first. Fluorination at the 6,7-position can be achieved by means of halogenation reaction and fluorine-containing halogenating reagents. Next, 4-hydroxyl groups are introduced through hydroxylation reaction. This step requires the selection of suitable hydroxylation reagents and reaction conditions to ensure the precise introduction of hydroxyl groups. Subsequently, a 2 - (ethylsulfanyl) group is introduced, which can be achieved by nucleophilic substitution reaction. Finally, 3-carboxylic acid ethyl ester is introduced, and the target compound is successfully synthesized through a series of reaction operations. The method starts with quinoline derivatives and reduces the complex steps of constructing quinoline rings.
