The method of preparing ethyl 6- (decyloxy) -7-ethoxy-4-oxo-1, 4-dihydroquinoline-3-carboxylate, can be carried out according to the following steps.
Take the appropriate starting material first, which should contain reactive functional groups, so as to construct the structure of the target molecule later. Aniline derivatives with suitable substituents can be selected, which are precursors to the construction of quinoline rings.
React this aniline derivative with suitable carbonyl compounds under suitable reaction conditions. This reaction may need to be carried out in a specific solvent, such as common organic solvents such as ethanol and toluene. And an appropriate amount of catalyst needs to be added to promote the reaction. The catalyst can be selected from acids or bases, depending on the characteristics of the reaction.
In the process of constructing a quinoline ring, the temperature and time of the reaction need to be finely regulated. Too high or too low temperature may affect the rate and yield of the reaction. Generally speaking, the reactants can be initially mixed and activated at a lower temperature, and then gradually warmed to a suitable reaction temperature for a period of time to allow the reaction to proceed fully.
After the quinoline ring structure is initially formed, the 6-position and 7-position substituent introduction steps are carried out. For the 6-position introduction (decyloxy) group, a suitable halogenated decane or decanol can be selected to react with the quinoline derivative under base catalysis. The alkali can be selected from potassium carbonate, sodium hydroxide, etc., and reacted in a suitable solvent, such as N, N-dimethylformamide (DMF), to facilitate the reaction.
The ethoxy group is introduced at position 7, and the haloethane or ethanol can be used to complete the substitution reaction under the same alkali-catalyzed conditions.
Finally, the carboxyl ethyl ester group is introduced at position 3. It can be achieved by reacting with the corresponding carboxylate reagent under specific conditions. This step also requires attention to the control of the reaction conditions to ensure the purity and yield of the product.
After each step of the reaction, the product needs to be separated and purified. Commonly used methods include column chromatography, recrystallization, etc. to remove impurities such as unreacted raw materials and by-products to obtain high-purity ethyl 6- (decyloxy) -7-ethoxy-4-oxo-1, 4-dihydroquinoline-3-carboxylate.
