---|---|---|
78% | With tetrakis(triphenylphosphine) palladium(0); potassium carbonate; In 1,4-dioxane; water; at 90℃; for 6h;Schlenk technique; | accurate weighing 2, 3 - b bromophenylacetic and [b] Thiophene (600 mg, 2.0 mmol), 5 - bromo -2 - hydroxy phenyl boronic acid (418 mg, 1.0 mmol), and in turn to 25 ml of in shu Lunke bottle, adding potassium carbonate (828 mg, 6 mmol), four (triphenylphosphine) palladium (0.05 equivalent), 1, 4 - dioxane/water (volume ratio 4:1), is 90 C reaction in oil bath 6 hours. After the reaction, the solvent is removed under reduced pressure, the use of silica gel column separation, petroleum ether/ethyl acetate as eluant, to obtain 4 - bromo -2 - (3 - bromophenylacetic and [b] Thiophene -2 - yl) phenol 3h, and the yield is 78%. |
