Procedure

To a solution of 6-chloro-1,1-dimethylindane (6.00 g, 0.0332 mol) in acetone (100 mL, 2 mol) was added 1.5 M of magnesium sulfate in water (30 mL) and potassium permanganate (12.3 g, 0.0780 mol). The reaction was stirred overnight, the resulting deposit was filtered, and the solution was concentrated to a reduced volume. The solution was extracted with EtOAc (3×100 ml) and the organic layer was concentrated. Purification by flash chromatography (10% EtOAc/hexanes) afforded the title compound (4.33 g, 67%) as a white solid.
