Методика

4-Methoxy-2,2',4',5,5'-pentachlorobiphenyl was prepared from 2,5-Dichloroanisole (35 g, 200 mmol) and 2,4,5-trichloroaniline (2.95 g, 15 mmol) according to the procedure in Example 2A. The excess dichloroanisole was removed by distillation and the residue was then filtered through silica gel (heptane eluent) and further purified [Chromatotron®, 4 mm silica gel, hexane, 20 mL/min] to give the product (980 mg). Mass spectrum: m/z at 354 for C13H7Cl5O.
