실험 절차
720 mL of acetyl chloride was added dropwise to 1200 mL of a methanol solution of 12.0 kg of (2R,3R,4S)-3,4,5-trihydroxy-2-hydroxymethyloxolane at a temperature of 15° C. or lower over 30 minutes, and the obtained mixture was then stirred at a temperature of 20° C. to 30° C. for 1 hour. Thereafter, 2100 mL of a 28% sodium methoxide/methanol solution and 1000 mL of toluene were added to the reaction mixture, and methanol was then distilled away under reduced pressure, to obtain 4500 mL of a toluene solution of (2R,3R,4S)-3,4-dihydroxy-2-hydroxymethyl-5-methoxyoxolane.
