To a 25 ml one-neck round bottom flask are added 1-indanol (10 g, 75 mmol) and aluminum phosphate (ALPO4, 1.0 g, 8.2 mmol). The contents of the flask are heated under partial vacuum (5-10 mm Hg) to distill over indene and water. The water is removed by pipette, with the last traces being removed by drying over anhydrous magnesium sulfate to give indene (8 g) in an isolated yield of 92 mole percent.
