Versuchsvorschrift

To a suspension of 6-chloro-3-nitropyridin-2-amine (6.3 g, 36.3 mmol) in ethanol (110 mL), 9.2 g (36.3 mmol) of iodine and 11.32 g (36.3 mmol) of silver sulphate were added. The crude mixture was stirred at room temperature overnight and the precipitate formed was filtered off. The solid isolated was purified by flash chromatography (1:1 hexane/ethyl acetate) to give the title compound (9.74 g, 88% of yield).
