Water → 5-Hydroxy-1-indanone

Participants

Reaction Steps

A suspension of 5-methoxy-1-indanone (10.3 g, 63.5 mmol) in toluene (150 mL) was ice-cooled, and aluminum chloride (16.9 g, 127 mmol) was added by small portions, and the mixture was heated under reflux under nitrogen atmosphere for 4 hr. The reaction mixture was allowed to cool to room temperature and poured into iced water. The organic product was extracted with a mixed solvent of ethyl acetate and tetrahydrofuran. The extract was dried over anhydrous magnesium sulfate and concentrated under reduced pressure to give 5-hydroxy-1-indanone as yellow crystals.
