To prepare 3-quinoline formonitrile, 4-chloro-7-fluoro-6-methoxy group, the following method can be used.
The starting material is selected from a suitable quinoline derivative, and its structure should contain a group that can be converted into the desired substituent in the subsequent reaction. Based on quinoline with a specific substitution pattern, it has a check point on the aromatic ring that can be substituted or modified, which is the basis for the introduction of the target substitution.
The quinoline precursor is first halogenated. In a suitable reaction system, such as with suitable halogenating reagents, such as chlorine and fluorine halogenating agents, under appropriate reaction conditions, such as suitable temperature, solvent and catalyst, chlorine atoms are introduced at position 4 and fluorine atoms are introduced at position 7. This halogenation step requires precise regulation of the reaction conditions, because the selectivity of the halogenation check point is extremely critical. Too high or too low temperature, or improper reagent ratio, may cause side reactions such as halogenation check point deviation or excessive halogenation.
Next, the methoxylation reaction is carried out. Select a suitable methoxylation reagent, such as a combination of methylation reagent and alkoxide salt, and introduce the methoxyl group into position 6 under a suitable alkaline environment and reaction temperature. In this process, factors such as alkalinity and reaction time will affect the efficiency and selectivity of methoxylation. If the alkalinity is too strong, methoxylation may also occur at other check points; if the alkalinity is insufficient, the reaction will be difficult to advance.
Then, convert the appropriate group on the quinoline ring into a cyano group. It can be achieved through a specific reaction path, such as using an appropriate cyanide reagent, under suitable reaction conditions. This step requires attention to the activity and reaction safety of the cyanide reagent, because it is highly toxic and dangerous.
After each step of the reaction is completed, appropriate separation and purification methods, such as column chromatography, recrystallization, etc. are required to remove impurities to obtain high-purity intermediate products and final products. In this way, 3-quinolinocarbonitrile and 4-chloro-7-fluoro-6-methoxy can be obtained by multi-step reaction and fine operation control.
