Reaction Steps
To a solution of [(2S,4S)-5-methoxy-4-(trifluoromethylsulfonyloxy)tetrahydrofuran-2-yl]methyl benzoate (compound 32c, 1.1 g, 2.8 mmol) in DMF (5 mL) was added sodium azide (372 mg, 5.7 mmol) at room temperature and the mixture was stirred at room temperature for 16 hours. The reaction mixture was diluted with water and extracted with EtOAc, the organic layers were combined and concentrated in vacuo to afford 1.1 g crude product of [(2S,4R,5R)-4-azido-5-methoxy-tetrahydrofuran-2-yl]methyl benzoate (compound 33a) as an oil, which was used in next step without further purification.
