Reaktionsschritte

To a degassed mixture of compounds 48 (1.10 mmol), 50 (1.10 mmol), and sodium carbonate (4.42 mmol) in a mixture of DMF and water (33 mL/3 mL) was added Pd(PPh3)4 (0.11 mmol). The reaction mixture was heated at 80° C. for 2 hrs. Ethyl acetate and water were added. The dried organic layers were evaporated in vacuo and the residue was purified by silica gel chromatography (eluent: DCM first; then DCM/MeOH 9/1) to give compound 51 as a beige solid in 59% yield. MS (ESI, EI+) m/z=744 (MH+).
