Third, use the Grignard reagent method. First prepare the Grignard reagent of 2,6-difluorophenyl, and then react with the titanium halide under anhydrous and anaerobic conditions to form an intermediate product. After that, introduce 1-methyl-2,4-cyclopentadiene and continue the reaction. Finally, the target product is obtained through separation, purification and other steps. However, in this process, the preparation of Grignard reagent needs to be handled carefully, because it is extremely sensitive to water and oxygen, and the reaction fails if it is not careful.
