Finally, 5-fluorine atoms are introduced. Or fluorine-containing reagents, such as Selectfluor, etc., can be used to react with the previous product under appropriate alkali and reaction conditions, and the fluorine atom can be introduced into the 5-position through nucleophilic substitution or other suitable mechanisms to obtain 5-fluoro-1 - [ (2-fluorophenyl) methyl] -3-iodine-1H-pyrazolo [3,4-b] pyridine. After each step of the reaction, the product should be separated and purified by means of column chromatography, recrystallization, etc., to ensure its purity and meet the needs of subsequent reactions or applications.
