How is 5-Fluoro-2-iodopyridine (CAS: 159870-80-1) typically synthesized?

5-Fluoro-2-iodopyridine is typically synthesized through a multistep process involving the iodination of 2-fluoropyridine followed by a nucleophilic substitution reaction. The synthesis often requires the use of iodine and a base like potassium carbonate as a catalyst. The reaction is carried out in an aprotic solvent like acetonitrile, yielding the target compound with good selectivity and moderate to high yield.
