5 - Fluoro - 1 - (2 - fluorobenzyl) - 3 - iodo - 1H - pyrazolo [3,4 - b] pyridine is an organic compound, and its common synthesis method is as follows:

The starting material is mostly selected with compounds containing pyridine structures and suitable substituents. If a specific pyridine derivative is used as a base, the pyridine ring is modified first. Or by halogenation reaction, the halogen atom is introduced at a specific position of the pyridine ring, such as with an appropriate halogenation reagent, under appropriate reaction conditions, the specific hydrogen atom on the pyridine ring is replaced by a halogen to introduce an iodine atom.
