Reaction Steps

1-[3-({[tert-Butyl(dimethyl)silyl]oxy}methyl)-2-fluorophenyl]-4,4′-bipiperidine (125 mg) and TEA (0.15 ml) were mixed with DCE (3 ml), and acetyl chloride (39 mg) was added thereto, followed by stirring at room temperature for 1 hour. A saturated aqueous sodium hydrogen carbonate solution and CHCl3 were added to the reaction mixture, and the organic layer was dried over Na2SO4 and concentrated under reduced pressure. The obtained residue was mixed with THF (3 ml), and a 1 M TBAF/THF solution (0.6 ml) was added thereto, followed by stirring at room temperature for 1 hour. To the reaction mixture were added an aqueous ammonium chloride solution and EtOAc, the organic layer was dried over Na2SO4, and the solvent was concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (hexane/EtOAc) to obtain 1-{1′-[2-fluoro-3-(hydroxymethyl)phenyl]-4,4′-bipiperidin-1-yl}ethanone (84 mg).
