Procedure
3-Oxabicyclo[3.1.0]hexane-2,4-dione (766 mg) was added to methanol (10 mL) at 0° C. After addition of triethylamine (0.953 mL), the mixture was stirred at room temperature for 1 hr. The solvent was evaporated. The residue was dissolved in ethyl acetate, washed with 1 N hydrochloric acid and brine, dried over magnesium sulfate and concentrated in vacuo to give the title compound (460 mg) as a colorless oil.
