Reaction Steps

To a solution of 2-(trimethylsilyl)ethyl (3R,4R)-4-hydroxy-6,6-dimethyl-tetrahydro-2H-pyran-3-ylcarbamate (360 mg, 1.25 mmol) and triethylamine (378 mg, 3.75 mmol) in dichloromethane (5 mL) was dropwise added mesyl chloride (213 mg, 1.87 mmol) at 0° C. The reaction mixture was stirred at room temperature for 4 h, and then diluted with dichloromethane (100 mL). The organic layer was washed with water (50 mL) and brine (50 mL), dried over sodium sulfate, filtered and concentrated to afford the title compound (550 mg, crude) as a yellow oil, which was directly used in the next step without further purification.
