実験手順

TEA (0.450 mL, 3.23 mmol) was added to a mixture of trans-(2-((tert-butyldiphenylsilyloxy)methyl)cyclopropyl)methanol (1 g, 2.94 mmol), methanesulfonyl chloride (0.250 mL, 3.23 mmol) and THF (10 mL) at 0° C., and the mixture was stirred at room temperature for 2 hr. To the reaction mixture was added water, and the mixture was extracted with ethyl acetate. The organic layer was washed with brine, and dried over magnesium sulfate, and the solvent was evaporated under reduced pressure to give trans-(2-(((tert-butyldiphenylsilyl)oxy)methyl)cyclopropyl)methyl methanesulfonate (1.230 g, 2.94 mmol, 100%) as a colorless oil.
