Procedure
A mixture of 3-Benzyl-[1,2,4]oxadiazole-5-carboxylic acid ethyl ester (360 mg, 1.6 mmol) and lithiumhydroxide-hydrate (65 mg, 1.6 mmol) in 10 mL MeOH and 5 mL water was stirred at room temperature for 1 h. The mixture was evaporated in vacuo to yield the crude product which was used in the next step without further purification.
