Reaction Steps

A solution of tert-butyl N-[[4-[5-[6-[(3aR,6aS)-6-(ethylsulfonylamino)-3,3a,4,5,6,6a-hexahydro-1H-cyclopenta[c]pyrrol-2-yl]-3-[bis(tert-butoxycarbonyl)amino]pyrazin-2-yl]-1,3,4-oxadiazol-2-yl]phenyl]methyl]-N-methyl-carbamate (110 mg, 0.14 mmol) in DCM (1 mL) was treated with TFA (1.0 g, 676 μL, 8.8 mmol). The reaction mixture was stirred for 1 hour. The solvent was evaporated and the residue was purified via reverse phase HPLC using 10 to 99% ACN in water (5 mM HCl modifier) to obtain N-[(3aR,6aS)-2-[5-amino-6-[5-[4-(methylaminomethyl)phenyl]-1,3,4-oxadiazol-2-yl]pyrazin-2-yl]-3,3a,4,5,6,6a-hexahydro-1H-cyclopenta[c]pyrrol-6-yl]ethanesulfonamide. LC/MS m/z 499.2 [M+H]+
