실험 절차

195 mg (3.0 mmol) of sodium azide were added to 2 ml of a DMF solution containing 328 mg (1.5 mmol) of 2,2-dimethyl-6-(3-chloro-2-oxopropyl)-1,3-dioxin-4-one prepared in Example 1, followed by stirring at room temperature for 10 minutes. Afterward, the solution was poured into ice water, extracted with ether, and then dried with anhydrous magnesium sulfate. After ether was distilled off, the residue was then subjected to column chromatography (an eluent of hexane:ethyl acetate=1:1), thereby obtaining 278 mg (yield 82%) of 2,2-dimethyl-6-(3-azido-2-oxopropyl)-1,3-dioxin-4-one.
