Procedure
Dissolve tert-butyl 6-fluoro-4-iodopyridin-3-ylcarbamate (1.47 g, 4.35 mmol) in DCM (20 mL). Add trifluoroacetic acid (TFA) (20 mL). Stir at RT under N2 for 2 h. Remove the solvent under reduced pressure. Dry in vacuo to afford 6-fluoro-4-iodopyridin-3-amine in TFA salt (1.02 g, 99%) with 100% HPLC purity. MS (ES) m/z 239 [M+1]+.
