To 5-bromo-1,2-dihydro-1-acenaphthylenol (0.25 g, 1 mmol) in dry THF (30 mL) was added chloro(tert-butyl)diphenylsilane (0.275 g, 1 mmol) and imidazole (0.34 g, 5 mmol), and the reaction stirred at room temperature under nitrogen for 18 h. The mixture was diluted with diethyl ether, filtered through a pad of silica, and evaporated in vacuo. Purification by flash chromatography on silica, eluting with ethyl acetate/hexane (1:9 to 1:1), yielded the title compound as a colourless oil.
