Reaction Steps
Phenylboric acid (366 mg, 3.0 mmols), palladium acetate (4.49 mg, 0.02 mmols), diadamantyl phosphine (12.1 mg, 0.04 mmols) and potassium triphosphate (1.273 g, 6 mmols) are placed in 6 ml of dioxane and water (0.18 ml, 10 mmols) under argon. The reaction mixture is heated in an oil bath of 100° C. and stirred for 5 minutes. Afterwards, 4-chloroanisole (0.27 ml, 2 mmols) is added. The reaction mixture is then stirred for 18 hours at 100° C. and subsequently cooled. The title compound is purified by flash chromatography over silica gel. The yield is 84%.
