실험 절차
Methyl 3-azido-2-O-benzyl-3-deoxy-D-glucopyranoside (93 mg) was dissolved in 0.84 mL of pyridine. Benzoyl chloride (45 μL) was added to the solution at −20° C. with stirring, and the mixture was stirred at −20° C. for one hr. Water (14 μL) was added thereto, and the mixture was stirred at −20° C. for 30 min. The contents were concentrated to dryness. Chloroform (10 mL) was added thereto, and the mixture was washed three times with 5 mL of a saturated aqueous sodium bicarbonate solution, three times with 5 mL of a 5% aqueous potassium bisulfate solution and three times with 5 mL of water, was dried over a Glauber's salt and was concentrated under the reduced pressure. The residue was purified by column chromatography on silica gel (25 g, hexane:ethyl acetate=3:1) to give the title compound (97 mg, yield 78%).
