The synthesis method of 4-hydroxy-7- (trifluoromethyl) quinoline has been known for a long time. There are many methods, and the number is as follows.
First, it starts with fluorobenzene-containing compounds and nitrogen-containing heterocyclic precursors. After condensation reaction, the synthesis path can be started. First, the two are put into a specific solvent, and a suitable catalyst is used to promote their binding, or they go through nucleophilic substitution, cyclization and other steps. Among them, the properties of the solvent, the amount of the catalyst and the reaction temperature are all critical. If the polarity of the solvent is improper, the reactants are difficult to miscible and the reaction is difficult; if there is too little catalyst, the reaction will be delayed; if the temperature is too high or low, side reactions can be clustered and the yield will < Br >
Second, with the help of transition metal catalysis strategy. Transition metals such as palladium and copper are used as the catalytic core to make suitable halogenated aromatics react with fluoroalkenyl amines with the help of ligands.

Third, starting from quinoline derivatives, through selective functionalization. First, quinoline with specific substituents is prepared, and then modified by hydroxylation and trifluoromethylation. Among them, suitable oxidizing agents and phenolizing reagents can be used for hydroxylation, and reagents containing trifluoromethyl can be selected for trifluoromethylation, and trifluoromethyl can be introduced by electrophilic or nucleophilic substitution. However, each step of modification needs to consider the influence of the original group to prevent it from overreacting or interfering with the introduction of new functional groups.

When preparing 4-hydroxy-7- (trifluoromethyl) quinoline, there are a number of urgent precautions that cannot be ignored.
The first thing to bear the brunt is the quality of the raw materials. Whether the raw materials are pure or not is directly related to the purity and yield of the product. The raw materials need to be carefully screened to check their purity and impurity content. If the raw materials contain too much impurities, the subsequent reaction or many side reactions will produce many side reactions, and the purification of the product will be more difficult.
The control of the reaction conditions is also crucial. Temperature needs to be precisely controlled. Reactions at different stages have their own suitable temperatures. If the temperature is too high, the reaction rate will increase, but the side reactions will also become more intense; if the temperature is too low, the reaction will be delayed or even stagnant. If the appropriate temperature for a certain step of the reaction is within a certain range, deviating from this range will affect the structure and yield of the product. Furthermore, the reaction time needs to be properly controlled. When the reaction is not reached, the raw materials may not be fully converted; if the reaction is excessive, the product may decompose or polymerize, which will damage the quality of the product. The use of
catalysts also needs to be used with caution. Catalysts can change the rate of chemical reactions, but their type and dosage need to be carefully considered. Choosing the right catalyst can greatly improve the reaction efficiency; improper dosage may cause the reaction to go out of control or fail to achieve the expected catalytic effect. The choice of
solvent should not be Solvents not only affect the solubility of the reactive substances, but also have a significant impact on the reaction rate and selectivity. Polar solvents and non-polar solvents are suitable for different types of reactions. Choose the wrong solvent, or the reaction cannot occur, or the product selectivity is poor.
The separation and purification of the product is also a key link. After the reaction, the product is often mixed with impurities, and suitable separation methods, such as extraction, distillation, recrystallization, etc., are required to obtain high-purity products. The operation process must be fine to avoid product loss or the introduction of new impurities.
To sum up, the preparation of 4-hydroxy-7- (trifluoromethyl) quinoline requires careful treatment in all aspects from the beginning of the raw material to the product.
