Dimethylformamide → HCID 22503528, compound

Participants

Reaction Steps

6-Benzyloxy-1-hexyne (5.60 g) and 2-bromo-benzaldehyde (2.90 g) were reacted in dimethylformamide (30 ml), in the presence of dichloro-bis-triphenylphosphinepalladium (0.40 g), cuprous iodide (0.20 g) and triethylamine (2.5 ml) in nitrogen atmosphere at 50° C. for 6 hr. The resulting reaction solution was evaporated, and ethyl acetate and water were added to the resulting residue. The resulting organic layer was washed with water and brine, and dried over magnesium sulfate. The solvent was evaporated, and the resulting residue was purified by silica gel column chromatography (ethyl acetate/hexane system), to give 2.60 g of the title compound as a pale yellow oil.
