Procedure

(2R,6S,13aS,14aR,16aS,Z)-ethyl 6-(tert-butoxycarbonylamino)-2-(4-fluoroisoindoline-2-carbonyloxy)-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]oxadiazacyclopentadecine-14a-carboxylate (0.093 g, 0.14 mmol) in THF (2 mL) was added 0.1 N NaOH solution (3.53 ml, 0.35 mmol) in H2O. The reaction was stirred at rt for 3 days. Water (5 mL) and ether (15 mL) was added. The aqueous layer was separated and acidified by saturated potassium hydrogen sulfate solution to pH=2˜3. The aqueous layer was extracted with EA (2×15 mL), washed with brine and dried over sodium sulfate. After removal of solvent, it (2R,6S,13aS,14aR,16aS,Z)-6-(tert-butoxycarbonylamino)-2-(4-fluoroisoindoline-2-carbonyloxy)-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]oxadiazacyclopentadecine-14a-carboxylic acid as white solid (0.074 g, 83%).
