Reaction Steps

1-Iodopyrrolidine-2,5-dione (NIS, 3.87 g, 17.2 mmol) was added in portions to 4-ethylpyridin-2-amine (2.00 g, 16.4 mmol) in AcOH (60 m) during 30 min at 65° C. The mixture was heated at 65° C. for 36 hours, was concentrated. The residue was purified by silica gel column chromatography (ethyl acetate/hexane 25 to 40%) to provide 4-ethyl-5-iodopyridin-2-amine: LC-MS: [(M+1)]+=249.00
