Versuchsvorschrift
A stirred suspension of 3-(2-pyridyl)-5-(3-alloxy-5-(methoxycarbonyl)phenyl)-1,2,4-oxadiazole (160 mg, 0.47 mmol) in methanol (5 mL) at ambient temperature was treated with 1 M sodium hydroxide (0.8 mL, 0.80 mmol). The reaction was stirred 16 hours and solvent was removed in vacuo. The residue was dissolved in a small amount of water and then acidified with 1 N hydrogen chloride. Extraction of the aqueous phase with dichloromethane followed by concentration in vacuo afforded 104.5 mg of 3-(2-pyridyl)-5-(3-alloxy-5-(hydroxycarbonyl)phenyl)-1,2,4-oxadiazole.
