What is the preparation method of 1-Ethyl-6,8-difluoro-1,4-dihydro-7- (3-methyl-1-piperazinyl) -4-oxo-3-quinolinecaboylic acid

1-Ethyl-6,8-difluoro-1,4-dihydro-7- (3-methyl-1-piperazinyl) -4-oxo-3-quinoline carboxylic acid, this is the name of the chemical substance. Its preparation method, although the ancient book "Tiangong Kaiwu" does not directly record the preparation of this specific substance, it can be deduced from the chemical ideas contained in it.

To make this substance, the first raw material should be selected. Compounds containing corresponding functional groups and suitable reactivity should be selected as starting materials. If the compound with quinoline parent nucleus is used as the base, because its structure is similar to the target product, the desired substituent can be added through subsequent reactions.

The initial preparation may require a nucleophilic substitution reaction. React with a nitrogen-containing heterocycle (such as 3-methyl-1-piperazine) with a suitable halogen to introduce the piperazine group to a specific position of quinoline. This step requires attention to the reaction conditions, such as temperature, solvent and catalyst selection. If the temperature is too high or the side reactions occur frequently, if it is too low, the reaction rate will be delayed. A suitable solvent should be able to dissolve the reactants without interfering with the reaction, and the catalyst can accelerate the reaction process.

Later, or involving fluorination reaction. To introduce fluorine atoms at positions 6 and 8 of the quinoline ring, a suitable fluorination reagent can be selected. This process is particularly strictly controlled by the reaction conditions. Due to the high activity of fluoride, it is easy to initiate a variety of side reactions. Or it needs to be operated under low temperature and inert gas protection to ensure precise substitution of fluorine atoms and reduce the generation of by-products.

When ethyl is introduced, an alkylation reaction can be used. Select a suitable ethylation reagent and react with quinoline derivatives under alkali catalysis. This step also requires careful regulation of the reaction conditions to ensure that the ethyl group is correctly connected to the target position.

After the introduction of each substituent is completed, or the functional groups need to be adjusted by oxidation, reduction and other reactions, the final product is 1-ethyl-6,8-difluoro-1,4-dihydro-7- (3-methyl-1-piperazinyl) -4-oxo-3-quinoline carboxylic acid. After each step of the reaction, the product should be purified by recrystallization, column chromatography and other means to remove impurities and maintain the purity of the product.
