Reaction Conditions

Reaction Steps

To a solution of 4′-chlorobiphenyl-4-ylamine (2.03 g, 0.01 mmol) in a mixed solvent system of methanol (10 ml) and distilled water (40 ml) is added potassium chlorate (0.830 g, 6.77 mmol) and potassium iodide (3.32 g, 0.02 mol). After heating the reaction mixture to 80° C., concentrated hydrochloric acid (0.60 ml) is added, and the mixture is further heated overnight at this temperature. The solution is cooled to room temperature and the crude product is extracted with diethyl ether (×3), followed by washing of the combined organic fractions with 5% aqueous sodium thiosulfate solution and distilled water. The organic phase is dried over anhydrous magnesium sulfate, filtered and the filtrate evaporated in vacuo to give a dark solid, which is triturated with hexanes to afford 4′-chloro-3-iodobiphenyl-4-ylamine (2.94 g) as light brown solid.
