実験手順
To a solution of {3-[(benzothiazol-2-yl)(1-methylpiperidin-4-yloxy)methyl]phenylsulfanyl}acetic acid methyl ester (30 mg) in absolute ethanol (1 mL) is added hydrazine hydrate (0.1 mL). The reaction mixture is heated at 80° C. for 18 hours. Solvent and volatiles are removed under reduced pressure. The residue is purified by chromatography (gradient dichloromethane/methanol from 95/5 to 80/20) to give {3-[benzothiazol-2-yl(1-methylpiperidin-4-yloxy)methyl]phenylsulfanyl}acetic acid hydrazide.
