Participants

Reaction Steps

To a solution of tert-butyl N-[[4-[5-[6-[(3aR,6aS)-6-amino-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 (150 mg, 0.22 mmol) and triethylamine (24 mg, 33 μL, 0.23 mmol) in DCM (1 mL) at 0° C. was added ethanesulfonyl chloride (29 mg, 21 μL, 0.22 mmol). The reaction mixture was stirred for 30 min. The solvent was evaporated and the crude material was purified via silica gel column chromatography using 10 to 70% EtOAc in DCM to obtain 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, 650%). LC/MS m/z 799.5 [M+H]+.
