3-Methoxyacetophenone → HCID 68877312, compound

Participants

Reaction Steps

1-(3-Methoxyphenyl)ethanone (15 g, 0.1 mmol) and methyl(triphenylphosphoranylidene)acetate (62 g, 0.186 mmol) in toluene (75 ml) were heated at 100° C. for 2 days. After allowing cooling to ambient temperature the solvent was removed under reduced pressure to give crude product. Precipitation with EtOAc and heptane followed by flash chromatography of the concentrated mother liquor on silica (eluent: 20% EtOAc in heptane) afforded the product as a mixture of geometric isomers (21.8 g, 86%).
