実験手順

5-(3-Aminothiophen-2-yl)[1,3,4]oxadiazol-2-ylamine hydrochloride (30 mg) is initially charged in 3 ml of acetonitrile. The equimolar solution of 2-chloro-4,5-difluorobenzoyl isocyanate in acetonitrile is added and stirred at RT. After 3 hours, the solid is filtered off with suction and dried under reduced pressure.
