Reaction Steps
(3R)-1-Benzyl-3-hydroxypyrrolidine (500 μl) and imidazole (466 mg) were dissolved in N,N-dimethylformamide (15 ml), tert-butyldiphenylsilyl chloride (1.57 ml) was added under ice cooling., and the mixture was stirred at room temperature for 9 days. After the solvent was distilled off under reduced pressure, and methylene chloride and water were added to the residue to conduct liquid separation, the resultant organic layer was dried over anhydrous sodium sulfate, and the solvent was distilled off under reduced pressure. The residue was subjected to flash column chromatography on silica gel (hexane:ethyl acetate=3:1) to obtain the title compound (1.27 g).
