Reaction Steps

To a solution of D-(+)-glucono-1,5-lactone (7.88 kg) and N-methylmorpholine (35.8 kg) in tetrahydrofuran (70 kg) was added trimethylsilyl chloride (29.1 kg) at 40° C. or below, and then the mixture was stirred at a temperature from 30° C. to 40° C. for 2 hours. After the mixture as cooled to 0° C., toluene (34 kg) and water (39 kg) were added thereto. The organic layer was separated and washed with an aqueous solution of 5% sodium dihydrogen phosphate (39.56 kg×2) and water (39 kg×1). The solvent was evaporated under reduced pressure to give the titled compound as an oil. The product was used in the next step without further purification.
