(2R,6S,13aS,14aR,16aS,Z)-6-(tert-butoxycarbonylamino)-14a-(cyclopropylsulfonylcarbamoyl)-5,16-dioxo-2,3,5,6,7,8,10,11,13a,14,14a,15,16,16a-tetradecahydro-1H-cyclopropa(j)pyrrolo[1,2-f][1,6,9]oxadiazacyclopentadecin-2-yl 4-fluoroisoindoline-2-carboxylate (0.037 g, 0.050 mmol) and Rh/Al (5%) (0.021 g, 0.010 mmol) in Ethyl acetate (5 mL) was charged with 1 atmosphere of hydrogen and stirred for 16 hrs. Water (3 mL) and saturated potassium hydrogen sulfate (3 mL) was added and stirred for 10 minutes. The organic phase was separated and aqueous phase extracted with ethyl acetate (10 mL), washed with brine and dried over sodium sulfate. After removal of solvent, the residue was purified by chromatography (Hexane:Ethyl acetate=1:2) to give (2R,6S,13aR, 14aR,16aS)-6-(tert-butoxycarbonylamino)-14a-(cyclopropylsulfonylcarbamoyl)-5,16-dioxohexadecahydro-1H-cyclopropa(j)pyrrolo[1,2-f][1,6,9]oxadiazacyclopentadecin-2-yl 4-fluoroisoindoline-2-carboxylate as white solid (0.014 g, 38%).
