반응 단계

Deoxo-Fluor® was added to a solution of 1,1-dimethylethyl 4-hydroxy-1,4′-bipiperidine-1′-carboxylate (0.500 g, 1.76 mmol) dropwise at −78° C. The mixture was maintained at −78° C. for 30 min before it was warmed to room temperature and stirred for 2 h. The mixture was washed with saturated aqueous sodium bicarbonate. The organic phase was dried over Na2SO4, filtered, and concentrated in vacuo. The crude material was purified via column chromatography (1:200 methanol/methylene chloride) to afford 1,1-dimethylethyl 4-fluoro-1,4′-bipiperidine-1′-carboxylate (0.300 g, 60% yield) as a colorless oil.
