To a stirred solution of 1-(4-hydroxyphenyl)-3-methylbut-2-en-1-one (1.0 g, 5.67 mmol) in dichlorobenzene (50 mL) was added aluminum chloride (1.97 g, 14.74 mmol). The mixture was heated to 150° C. for 4 hours. After cooled to room temperature, the reaction mixture was poured over ice and extracted with dichloromethane (3×80 mL). The organic layers were combined, dried over magnesium sulfate, filtered, and concentrated. The residue was purified on a silica gel column (20% ethyl acetate in hexane) to give 5-hydroxy-3,3-dimethylindan-1-one as a tan solid (0.32 g, 32%). MS m/z 177.
