Aqueous ethyl acetate 1M-HCl (3 mL) was added to 1-hydroxy-5-methoxy-3-(oxiran-2-ylmethoxy)-9H-xanthen-9-one (30 mg, 0.10 mmol) synthesized in Step 2 of Example 1, followed by stirring at room temperature for 30 minutes, and the reaction solvent was removed under reduced pressure. Ether was added to the residue, followed by sonication, and the solvent was removed to obtain the title compound (31 mg, 92%) as a light brown solid.
