4-AMINO-3,5-DIIODOPYRIDINE Use and Manufacturing
In the reaction flask, 500 mL of methanol was added successively, 3000 mL of water, 4-aminopyridine 94.11 g (1.0 mol), Potassium iodide 224.10 g (1.35 mol), Potassium iodate 149.80 g (0.70 mol), 20 slowly dropping concentrated hydrochloric acid 160mL, After dripping for 3 hours, the reaction was continued for 1 hour after the dropwise addition, and then a 50 mL aqueous solution of 17.73 g (0.20 mol) of sodium chlorite was added dropwise. After the addition was continued, the reaction was continued for 0.5 hour in a high performance liquid chromatography After the monitoring reaction was completed, the reaction solution was diluted with 4000 mL of water, Add 6000 mg of extractant trichloromethane in three portions, The combined organic phase was washed once with sodium salt containing sodium thiosulfate, Washed with sodium bicarbonate salt once, separated, dried over anhydrous magnesium sulfate, The solvent was withdrawn from the solvent to give the crude product of gray 3, 5-diiodo-4-aminopyridine, The crude product was recrystallized from a mixed solvent of ethanol and water to give 318.23 g of a white crystalline solid in a yield of 92.0percent, a
