実験手順

A solution of 57.0 grams (0.226 mole) of 3-ethoxy-4-oxahexyl benzoate in 475 ml of tetrahydrofuran and 475 ml of aqueous 10% hydrochloric acid was stirred at ambient temperature for 18 hours. After this time the reaction mixture was stirred with 700 ml of diethyl ether. The organic layer was separated, washed with water, and then was dried with sodium sulfate. The mixture was filtered, and the filtrate was concentrated under reduced pressure yielding 28.0 grams of 3-oxopropyl benzoate. The nmr spectrum was consistent with the proposed structure.
