Yield:13803-39-9 97%

Reaction Conditions:

with tetrakis(triphenylphosphine) palladium(0);potassium carbonate in ethanol;water;toluene for 4 h;Inert atmosphere;Reflux;

Steps:

4.1 (1) Synthesis of 5-phenylfuran-2-carbaldehyde (Compound Z-4)
Under the strict protection of argon, 0.875 g (0.005 mol) of 5-bromo-2-furancarboxaldehyde, 0.610 g (0.005 mol) of phenylboronic acid dissolved in 20 mL of toluene, 20 mL of ethanol, and 5 mL of an aqueous 2 mol / L potassium carbonate solution was heated to reflux for 4h. After completion of the reaction, it was left to stand. The aqueous layer was removed. The aqueous layer was washed three times with ethyl acetate. The washing solution and the reaction solution were combined. The solvent was distilled off under reduced pressure. Column chromatography separation gave pure product 0.836g, yield of about 97%.
