2-[3-(3-Bromo-phenyl)-cyclobutyl]-ethanol (0.500 gm, 1.96 mmol) was dissolved in diethylether (7 mL) and combined with tetrabutylammonium iodide (75 mg, 0.203 mmol), an aqueous solution of sodium hydroxide (5 gm, 50% wt/wt, 62.5 mmol) and dimethylsulfate (0.50 ml, 5.27 mmol). The mixture was stirred overnight at ambient temperature then diluted with diethyl ether and decanted. The supernatant was concentrated onto silica and purified by column chromatography (25% diethylether in hexanes) to afford 389 mg of an oil (74%). This material was used in next step without further characterization.
