A solution of 1,3-dimethoxy-2-propanol (361.5 mg, Tyger) in tetrahydrofuran (4 ml) was added with sodium iodoacetate (624.6 mg, Spectrum), and successively added with sodium hydride (198 mg, Wako Pure Chemical Industries) as several portions at 0° C., and the mixture was stirred at the same temperature for 30 minutes, and then further stirred at room temperature for 15.5 hours. The reaction mixture was cooled again to 0° C., and then carefully added with water and then with chloroform, and the organic layer was separated. The aqueous layer was acidified (pH 4) with 1 N hydrochloric acid, and extracted three times with chloroform, and the combined organic layer was washed with saturated brine, and dried over anhydrous magnesium sulfate. Then, the solvent was evaporated under reduced pressure to obtain the title compound (206.5 mg).
