First take (1R, 3S) -trans-3- (2,2-dichlorovinyl) -2,2-dimethylcyclopropanecarboxylic acid in an appropriate amount and place it in a clean reactor. Another 2,3,5,6-tetrafluorobenzyl alcohol is prepared and slowly added to the kettle to catalyze with a specific catalyst. This catalyst needs to be carefully selected, and its activity and selectivity have a great impact on the reaction effect.

The reaction temperature also needs to be precisely controlled to maintain a suitable range. If it is too low, the reaction will be slow, and if it is too high, it will cause side reactions. During the reaction, pay close attention to changes in the kettle, such as fluctuations in temperature and pressure, and changes in the concentration of reactants and products. < Br >
After the reaction is completed asymptotically, the target product is separated and purified from the reaction mixture by suitable separation means, such as extraction, rectification, etc. The choice of extractant is related to the purity and yield of the product, which needs to be determined by repeated experiments.
