Benzene → 2,2-Dibutyl-4-hydroxy-1-indanone

Participants

Reaction Steps

A mixture of 4-(tert-butyldimethylsilyl)oxy-1indanone (524 mg), 1-iodobutane (0.91 ml), and potassium tert-butoxide (896 mg) in dry benzene (15 ml) was refluxed for 2 hours under nitrogen. The reaction mixture was allowed to cool and poured into water. The separated oil was extracted with ethyl acetate. The organic layer was washed with brine, and concentrated in vacuo. The residue was subjected to column-chromatography on silica gel (elution by 10% n-hexane in dichloromethane and then dichloromethane) to yield 2,2-dibutyl-4-hydroxy-1-indanone (150 mg) as crystals.
