Reaction Steps
Following the procedure for 19, 7 (0.868 g, 1.95 mmol), 11 (0.535 g, 1.95 mmol), tetrakis(triphenylphosphine)palladium(0) (112 mg, 97.2 μmol), Na2CO3 (1.59 g, 15.0 mmol), H2O (15 mL) and THF (25 mL) yielded 20 (0.81 g, 81%) as a white solid after flash chromatography (SiO2, 100% CH2Cl2 to 19:1 CH2Cl2-acetone).
