A solution of tert-butyl N-[5-[(3aR,6aS)-6-oxo-1,3,3a,4,5,6a-hexahydrocyclopenta[c]pyrrol-2-yl]-3-(5-phenyl-1,3,4-oxadiazol-2-yl)pyrazin-2-yl]-N-tert-butoxycarbonyl-carbamate (57 mg, 0.10 mmol) in DCM (1 mL) was treated with TFA (1.5 g, 1 mL, 13 mmol) The reaction mixture was stirred at room temperature for 1 h. The solvents were evaporated and the residue was dissolved in DMF and purified by reverse phase column chromatography to obtain (3aR,6aS)-2-[5-amino-6-(5-phenyl-1,3,4-oxadiazol-2-yl)pyrazin-2-yl]-1,3,3a,4,5,6a-hexahydrocyclopenta[c]pyrrol-6-one.
