Reaction Steps

To a solution of 4-iodobenzonitrile (0.458 g, 2 mmol), 4-methoxyphenol (0.372 g, 3 mmol) and cesium carbonate (1.30 g, 4 mmol) in dioxane (4 mL) was added N,N-dimethylglycine hydrochloride (0.025 g, 0.18 mmol). The vessel was purged with nitrogen before Cu(I) iodide (0.014 g, 0.07 mmol) was added. The reaction mixture was heated to 90° C. overnight. The reaction mixture was diluted with water and ethyl acetate. The organic portion was washed with brine, dried over anhydrous Na2SO4 and concentrated in vacuo to give the title compound (0.51 g, 100%); 1H NMR (400 MHz, CDCl3); δ 3.83 (s, 3H), 6.92-7.02 (m, 6H), 7.56-7.58 (m, 2H).
