Procedure
Reaction of 4-(4-aminophenyl)-1,2,5-oxadiazol-3-amine with 2-benzyl-2-azabicyclo[2.2.1]heptan-7-one (J. R. Malpass, S. Handa, and R. White, Org. Lett., 2005, 7, 2759-2762) affords the title compound as the benzyl-protected amine. Purification by chromatography followed by removal of the benzyl group by hydrogenolysis affords the title amine.
