実験手順
Succinic anhydride (14 mg, 0.14 mmol) and [3-(N-hydroxycarbamimidoyl)-phenyl]-carbamic acid tert-butyl ester (35 mg, 0.14 mmol) were dissolved in 0.25 mL DMF and heated at 120° C. for 2 h. The cooled solution was evaporated and dried to yield 3-[3-(3-tert-butoxycarbonylamino-phenyl)-[1,2,4]oxadiazol-5-yl]-propionic acid which was used without further purification.
