How is 1-Fluoro-3-iodo-5-methylbenzene (CAS: 491862-84-1) typically synthesized?

1-Fluoro-3-iodo-5-methylbenzene (CAS: 491862-84-1) is typically synthesized via a fluorination and iodination process. The starting material, 5-methylbenzofluoride, is treated with iodine in the presence of a Lewis acid catalyst such as aluminum chloride to form the intermediate. Further treatment with other reagents leads to the final product. The overall process yields up to 90% of the target compound, with good selectivity and purity.
