A mixture of α-tetralone (200 mL, 1.5 mol) and conc. H2SO4 (4 mL) in isopropenyl acetate (1.0 L, 9.08 mol) was heated to reflux overnight. It was cooled to r.t. and filtered through a mixture of celite, NaHCO3 and silica (approx. 1:1:0.2) with EtOAc and concentrated to yield 317.1 g of the crude title product; bp: 90° C./0.5 mm Hg.
