反応手順

To a solution of 222 mg of 1-methanesulfonyloxymethyl-cyclopropane carboxylic acid ethyl ester in 5 mL of tetrahydrofuran was added 3 mL of 2M dimethyl amine in tetrahydrofuran, and stirred at room temperature for 3 days. The solvent was distilled off, and the residue was added with 2 mL of 1N hydrochloric acid, and washed with diethyl ether. The aqueous layer was added with 10% potassium carbonate aqueous solution, and extracted with ethyl acetate. The extracted layer was washed with saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated, to afford 56 mg of the title compound as a pale yellow oil.
