Procedure

(2R,6S,13aS,14aR,16aS,Z)-ethyl 6-(tert-butoxycarbonylamino)-2-(4-fluoroisoindoline-2-carbonyloxy)-9-(2-nitrophenylsulfonyl)-5,16-dioxo-1,2,3,5,6,7,8,9,10,11,13a,14,14a,15,16,16a-hexadecahydrocyclopropa(n)pyrrolo[2,1-c][1,4,9]triazacyclopentadecine-14a-carboxylate (1.45 g, 1.72 mmol) in THF (22 mL) was added 0.4 N NaOH solution (10.8 ml, 4.30 mmol) in water. The reaction was stirred at rt for 6 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 (2×30 mL). the combined organics were washed with brine and dried over sodium sulfate. After removal of solvent, it gave (2R,6S,13aS,14aR,16aS,Z)-6-(tert-butoxycarbonylamino)-2-(4-fluoroisoindoline-2-carbonyloxy)-9-(2-nitrophenylsulfonyl)-5,16-dioxo-1,2,3,5,6,7,8,9,10,11,13a,14,14a,15,16,16a-hexadecahydrocyclopropa(n)pyrrolo[2,1-c][1,4,9]triazacyclopentadecine-14a-carboxylic acid as white solid (1.40 g, 99%).
