To a solution of 6.52 g (40 mmol) of 2,4-dichlorophenol and 7.76 g (52 mmol) of sodium iodide in 80 mL of acetonitrile and 16 mL of water at room temperature add 5.64 g (52 mmol) of tert-butyl hypochlorite dropwise over a period of 30 minutes. Stir the reaction mixture for 3 hours at ambient temperature. Dilute the reaction mixture with 200 mL of ethyl acetate. Wash the resulting organic solution successively with 5% aqueous sodium thiosulfate solution and brine and dry over anhydrous magnesium sulfate. Remove the solvent and then crystallize from hexanes to yield 5.9 g (51%) of (P9) as a slightly colored solid.
