Vorschrift

To a stirred solution of 1-fluoro-4-nitrobenzene (10 mmol) in DMF (20 mL) at rt, solid potassium carbonate (30 mmol) was added followed by addition of 2,4-dichlorophenol (10 mmol) to the reaction mixture and heating to 80° C. until the reaction was complete as indicated by TLC or HPLC. After cooling to rt, the reaction mixture was poured into H2O (100 ml), extracted with EtOAc (2×50 mL), washed with H2O (2×50 ml) and brine (50 ml), and dried over sodium sulfate. The solvent was removed in vacuuo to afford the desired 4-(2,4-dichloro-phenoxy)-1-nitrobenzene. The crude product was used for further transformation.
