Reaction Steps

Methyl 3,6-anhydro-2-O-methyl-β-D-glucofuranoside (420 mg, 2.6 mmol) was dissolved in dichloromethane (10 mL) and pyridine (0.36 mL, 3.7 mmol) at 0° C. Methanesulfonyl chloride (0.14 mL, 3.1 mmol) was added and the resulting mixture was stirred at 0° C. for 1 hour then at room temperature for 2 hours. The reaction mixture was washed with water and saturated aqueous sodium bicarbonate solution, dried over anhydrous sodium sulfate, filtered and concentrated to give methyl 3,6-anhydro-2-O-methyl-5-O-(methylsulfonyl)-β-D-glucofuranoside as a colorless oil, 669 mg, 95% yield, which was used without further purification.
