The synthesis of 2 + - (ethylthio) -6,7 -difluoro-4-hydroxy-3-quinoline carboxylic acid ethyl ester is a key content in organic synthesis. The synthesis method of this compound can be obtained according to the traditional process wisdom contained in "Tiangong Kaiwu" and combined with modern chemical knowledge and technology.
First, it is necessary to choose a suitable starting material. Usually a compound containing quinoline structure is used as a base, supplemented by reagents containing ethylthio, fluorine atoms, hydroxyl groups and ethyl ester groups. If a specific quinoline derivative is used as the starting point, the characteristics of its structure determine the direction and difficulty of the reaction. This starting material needs to undergo a multi-step reaction to gradually introduce the required functional groups. < Br >
First look at the introduction of fluorine atoms. The method of nucleophilic substitution can be used. Under suitable reaction conditions, fluorine-containing reagents, such as potassium fluoride, are introduced into the specific position of the quinoline structure. During the reaction, it is necessary to control the temperature and time, and choose an appropriate solvent to assist the reaction. Commonly used solvents such as dimethylformamide (DMF), whose polarity can promote the smooth occurrence of ionic reactions.
The second time is the introduction of ethylthio. Sulfur-containing reagents, such as sodium ethanethiol, can react with appropriately activated quinoline intermediates. This reaction also requires strict regulation of conditions, such as reaction temperature and pH. The amount of alkali needs to be accurate. Too much or too little will affect the yield and selectivity of the reaction.
Furthermore, the introduction of hydroxyl groups. Or by hydrolysis reaction, some functional groups that are easy to hydrolyze can be converted into hydroxyl groups. This process requires a high pH of the reaction environment. Peracid or perbase may cause side reactions to occur, affecting the purity of the target product.
As for the formation of ethyl ester groups, the common method is to esterify ethanol and corresponding carboxylic acids in the presence of a catalyst. Concentrated sulfuric acid is often used as a catalyst for this reaction, but attention should be paid to its corrosiveness and control of reaction conditions to prevent side reactions such as carbonation.
The whole synthesis process requires multiple steps of reaction, each step needs to be carefully operated and monitored. After each step of reaction, it needs to be separated and purified, such as column chromatography, recrystallization, etc., to remove impurities and obtain a high-purity target product 2 + - (ethylthio) -6,7 -difluoro-4-hydroxy-3-quinoline carboxylic acid ethyl ester. In this way, a satisfactory synthesis effect can be obtained.
