Participants

Reaction Steps

Acetic anhydride (5 ml) was added to 2-[2-hydroxy-3-(o-tolyloxy)phenyl]-n-nonanoic acid (4.3 g), and the mixture was refluxed under heating for 10 minutes and evaporated under reduced pressure. The residue was purified by column chromatography (silica gel 60 g, benzene) to give 3-(n-heptyl)-7-(o-tolyloxy)-2,3-dihydrobenzofuran-2-one (3.0 g).
