Tributylphosphine → HCID 23082914, compound

Participants

Reaction Steps

A solution of methyl 3-(4-hydroxyphenyl)propanoate (0.360 g, 2.00 mmol), [3-(1-phenylvinyl)phenyl]methanol (0.421 g, 2.00 mmol) and tributylphosphine (0.747 mL, 3.00 mmol) in toluene (30 mL) was stirred under ice-cooling, 1,1′-(azodicarbonyl)dipiperidine (0.757 g, 3.00 mmol) was added by small portions under a nitrogen atmosphere, and the mixture was stirred at room temperature for 18 hrs. Hexane (15 mL) was added to the reaction mixture, the precipitated insoluble material was filtered off, and the filtrate was concentrated under reduced pressure. The residue was purified by silica gel chromatography (hexane-20% ethyl acetate/hexane) to give the title compound as a colorless oil (0.641 g, yield 86%).
