To a solution of cis-3-(benzyloxymethyl)cyclobutanol (Albany Molecular, 0.76 g, 4.0 mmol) in THF (10 mL) at 0° C. was added sodium hydride (0.47 g, 11.9 mmol). The mixture was stirred at 0° C. for 15 min then iodomethane (0.37 mL, 5.9 mmol) was added. The mixture was stirred for 5 min then the ice-bath was removed and the mixture was stirred at ambient temperature for 16 h. The mixture was quenched with 5 mL saturated, aqueous NaHCO3 and diluted with 5 mL EtOAc. The layers were separated and the aqueous layer was extracted with EtOAc (3×5 mL). The combined organics were dried over anhydrous Na2SO4, filtered, concentrated under reduced pressure and purified via column chromatography (SiO2, 75% hexanes/EtOAc) to provide the title compound (0.69 g, 3.3 mmol, 85% yield). MS (DCI/NH3) m/z 207 (M+H)+.
