Reaction Steps
12 g of 6-hydroxy-2H-pyran-3(6H)-one was dissolved in 100 ml of methylene chloride, and the solution was cooled to 0° C. Then, 11.4 g of ethyl chlorocarbonate was added, and a solution comprising 10.6 g of triethylamine and 20 ml of methylene chloride was dropwise added thereto. The mixture was stirred for 3 hours, and the reaction mixture was poured into ice water and extracted with methylene chloride. The solvent was distilled off under reduced pressure, and the residue was subjected to distillation under reduced pressure to obtain 12.3 g (yield: 63%) of the above-identified compound.
