Procedure

To a mixture of 23 g (0.095 mol) of 1-(3-methoxyphenyl)-indan-1-ol and 100 mg of p-toluene sulfonic acid monohydrate was added 1 L of toluene and the solvent was distilled in vacuo (40 mm) until an oil residue was obtained. The oil was chromatographed (silica, 1:1 hexane/methylene chloride) to afford 17.0 g (80.1%) of 1-(3-methoxyphenyl)-indene as a pale yellow oil.
