Participants

Reaction Steps

To a solution of [(2S,4S)-5-methoxy-4-(trifluoromethylsulfonyloxy)tetrahydrofuran-2-yl]methyl benzoate (compound 32c, 400 mg, 1.04 mmol) in DMF (3 mL) was added pyrrolidine (142 mg, 2.0 mmol) at room temperature and the mixture was stirred at room temperature for 16 hours. The reaction mixture was diluted by water and extracted with EtOAc, the organic layers were combined and concentrated in vacuo to afford 230 mg crude product of [(2S,4R)-5-methoxy-4-pyrrolidin-1-yl-tetrahydrofuran-2-yl]methyl benzoate (compound 32d) as an oil, which was used in next step without further purification. MS obsd. (ESP) [(M+H)+]: 306.
