Reaction Steps
An aqueous 1 M sodium hydroxide solution (7.65 ml) was added to a THF (20 ml) solution containing 5-[(acetoxy)methyl]pyridin-3-yl 4-{4-[(3-fluorobenzyl)oxy]phenoxy}piperidine-1-carboxylate oxalate (1.10 g), followed by stirring at 65° C. for 3 hours. The reaction liquid was neutralized with 1 M hydrochloric acid, followed by extraction with chloroform and drying over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography (eluent: chloroform:methanol=12:1 (v/v)) to obtain 5-(hydroxymethyl)piperidin-3-yl 4-{4-[(3-fluorobenzyl)oxy]phenoxy}piperidine-1-carboxylate (770 mg).
