実験手順
To a mixture of 16.3 g of the above alcohol in 400 ml of toluene was added 100 mg of p-toluenesulfonic acid and the mixture was placed on a Rotovap® and the solvent was distilled in vacuo (40 mm/50° C.) until a brown-red residue was obtained yielding 14.3 g (96%) of 4,5-dihydro-7-(3-furyl)-benzofuran as a red oil.
