実験手順

To a solution of 4-amino-3-nitro-benzoic acid methyl ester (4.6 g, 23.45 mmol) in ethanol (120 mL) was added iodine (8.33 g, 32.83 mmol), followed by Ag2SO4 (10.24 g 32.83 mmol). The mixture was stirred overnight at room temperature and then filtered. The filtrate was concentrated under reduced pressure and the residue was purified by column chromatography to give 4.98 g (66%) of 4-amino-3-iodo-5-nitro-benzoic acid methyl ester.
