Reaction Conditions

Reaction Steps

An aqueous 1 M sodium hydroxide solution (3.24 ml) was added to a THF (10 ml) solution containing 5-[4-(ethoxycarbonyl)piperidin-1-yl]pyridin-3-yl 4-{4-[(3-fluorobenzyl)oxy]phenoxy}piperidine-1-carboxylate oxalate (240 mg), followed by stirring at 60° C. for 5 hours. 1 M hydrochloric acid (3.24 ml) was added to the reaction solution and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (eluent: chloroform:methanol=10:1 (v/v)). The resulting oil was dissolved in ethanol/water, then oxalic acid (24 mg) was added thereto for crystallization to obtain 1-(5-{[(4-{4-[(3-fluorobenzyl)oxy]phenoxy}piperidin-1-yl)carbonyl]oxy}pyridin-3-yl)piperidine-4-carboxylic acid oxalate (93 mg).
