Reaktionsschritte

To a solution of 4-methoxyphenol (3.99 g, 32.17 mmol) and 4-bromobiphenyl (5 g, 21.45 mmol) in anhydrous dioxane (40 mL) were added cesium carbonate (13.98 g, 42.9 mmol) and N,N-dimethylglycine.HCl (0.898 g, 6.4 mmol). The reaction mixture was flushed with nitrogen. Copper (I) iodide (0.408 g, 2.145 mmol) was added and the reaction mixture was stirred at 90° C. for 18 h under an atmosphere of nitrogen. The mixture was diluted with water (100 mL) and extracted with EtOAc (250 mL). Aqueous layer was re-extracted with EtOAc (150 mls). The organic layers were combined, dried over anhydrous Na2SO4, and concentrated to obtain the title product 7.84 g.
