Procedure

To a mixture of 5 g (0.024 mol) of 1-(3-furyl)-indan-1-ol in 500 mL of toluene was added 50 mg of p-toluenesulfonic acid monohydrate and the solvent was distilled in vacuo (40 mm) until a residue was obtained. The residue was chromatographed (silica, 1:1 hexane/methylene chloride) to afford 2.7 g (61.3 %) of 1-(3-furyl)-indene as a clear oil.
