To prepare 1% 2C5-difluoro-3-chloro-2- (4-cyanophenoxy) benzene (9Ci), the method is as follows:
First take an appropriate amount of 4-cyanophenol, place it in a clean reactor, add an appropriate amount of alkali, such as potassium carbonate, stir well, so that the alkali and 4-cyanophenol can fully react to form a phenolic salt. This process needs to pay attention to the reaction temperature, which should be maintained at a mild room temperature. The stirring speed should also be moderate, so that the two can fully contact the reaction.
Then, slowly add 1% 2C5-difluoro-3-chlorobenzene to it. The dropwise addition process must be slow to prevent the reaction from being too violent. After the dropwise addition is completed, raise the reaction temperature to a certain extent, such as 80-100 ° C, maintain this temperature and continue to stir, so that the nucleophilic substitution reaction between the two fully occurs. The reaction time is about several hours, and the reaction process needs to be closely monitored. The reaction can be tracked by means of thin-layer chromatography (TLC). When the raw material point is basically eliminated, the reaction is regarded as basically completed.
After the reaction is completed, the reaction mixture is cooled to room temperature, and then an appropriate amount of water is added for quenching. Subsequently, an organic solvent such as dichloromethane is extracted to collect the organic phase. The organic phase is dried with a desiccant such as anhydrous sodium sulfate to remove the moisture. After that, the organic solvent is removed by reduced pressure distillation to obtain a crude product.
Finally, the crude product is purified. Column chromatography can be used to select a suitable eluent, such as petroleum ether and ethyl acetate mixed in a certain proportion of the elution system, for separation and purification, collect the fraction containing the target product, spin steam to remove the solvent, that is, to obtain a pure 1% 2C5-difluoro-3-chloro-2- (4-cyanophenoxy) benzene (9Ci). The whole preparation process requires strict control of the reaction conditions and operation details of each step to ensure the purity and yield of the product.
