On its electrophilicity, the electron cloud distribution of the quinoline ring is different due to the presence of chlorine atoms and methoxy groups in the molecular structure. The chlorine atom has an electron-absorbing effect, which reduces the electron cloud density of the quinoline ring. In the electrophilic substitution reaction, the activity of specific positions attacked by electrophilic reagents is different. This electron-absorbing property also affects its interaction with nucleophiles.
Looking at its alkalinity, the quinoline ring is weakly basic, but the power supply of the methoxy group may be fine-tuned. Methoxy groups can increase the density of electron clouds on the ring, enhancing its alkalinity to a certain extent. This alkaline characteristic enables it to react with acids to form corresponding salts.
In terms of solubility, the polarity of the molecule changes due to the chlorine atom and methoxy group. In organic solvents, such as ethanol, dichloromethane, etc., or have a certain solubility. However, in water, due to the large proportion of non-polar quinoline rings, the solubility may be limited.

In this process, concentrated sulfuric acid is both a dehydrating agent and an oxidizing agent, which prompts the reaction to proceed according to a specific path. However, this method needs to pay attention to the control of the reaction temperature. If the temperature is too high, side reactions can easily occur, which affects the purity and yield of the product.
The second is the Combes synthesis method. The p-chloro-anthranilyl anisole and β-dicarbonyl compound are reacted under acid catalysis. The intermediate product is first formed by condensation, and then the quinoline derivative is obtained by cyclization. The advantage of this route is that the reaction conditions are relatively mild, the requirements for reaction equipment are slightly lower, and there are few side reactions, which is conducive to improving the purity of the product. However, the choice and dosage of β-dicarbonyl compounds have a great influence on the reaction results and need to be carefully considered.
The third is the Doebner-von Miller synthesis method. The reaction of p-chloroaniline and acral in an acidic medium in the presence of an oxidizing agent. The quinoline skeleton was constructed by addition, cyclization and other processes. The key to this method lies in the type and dosage of oxidants. Different oxidants will make the reaction rate and product distribution different. And the acidity of the reaction system also needs to be precisely controlled to ensure the smooth progress of the reaction.
All these methods have advantages and disadvantages. In the actual synthesis, 4-chloro-8-methoxy quinoline can be synthesized efficiently when considering the availability of raw materials, the feasibility of reaction conditions, the purity and yield of the product, etc.
