참여 물질

반응 단계

To a solution of cis-3-benzyloxymethylcyclobutanol (Albany Molecular Research Institute, 1.0 g, 5.2 mmol) in 10 mL of tetrahydrofuran at 0° C. was added NaH (0.62 g, 15.6 mmol). The mixture stirred for 15 minutes then iodomethane (0.49 mL, 7.8 mmol) was added and the mixture was allowed to warm to ambient temperature and stir for 16 hours. Some starting material remained by TLC so additional NaH (0.21, 5.2 mmol) and iodomethane (0.32 mL, 5.2 mmol) were added and the mixture stirred for an additional 2 hours. The mixture was quenched with 10 mL of NH4Cl and diluted with 10 mL of ethyl acetate. The layers were separated and the aqueous layer was extracted 2×5 mL of ethyl acetate. The combined organic extracts were dried over anhydrous Na2SO4, filtered and concentrated under reduced pressure. Purification via column chromatography (SiO2, 75% hexanes in ethyl acetate) afforded the title compound. MS (DCI/NH3) m/z 207 (M+H)+.
