Reaction Steps

A stirred, cooled (ice bath) solution of 6-bromo-8-methoxy-4,4-dimethyl-3,4-dihydro-2H-naphthalen-1-one (Intermediate 64, 0.24 g, 0.83 mmol) in anhydrous dichloromethane (4 mL) was treated with aluminum chloride (0.4 g, 3 mmol). The reaction mixture was allowed to warm to ambient temperature and stirred overnight. It was poured into water and extracted with dichloromethane and ethyl acetate. The combined organic phase was dried over anhydrous magnesium sulfate, filtered and evaporated in vacuo to a brown oil that was subjected to flash column chromatography over silica gel (230-400 mesh) using 10% ethyl acetate in hexane as the eluent to afford the title product as a pale yellow solid (0.13 g, 56%).
