실험 절차

(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 (0.71 g, 0.87 mmol) in toluene (10 mL) was added di(1H-imidazol-1-yl)methanone (0.18 g, 1.13 mmol) in rt. The reaction was stirred at 60° C. for 3 hrs. Cyclopropanesulfonamide (0.16 g, 1.31 mmol) was added, followed by addition of DBU (0.26 ml, 1.74 mmol). The reaction was then stirred at rt for 17 hrs. Water (5 mL) was added and acidified with saturated potassium hydrogen sulfate until pH=2˜3. The mixture was extracted with ethyl acetate (20 mL), washed with brine and dried over sodium sulfate. After removal of solvent, the residue was purified by chromatography (Ethyl acetate) to give (2R,6S,13aS,14aR,16aS,Z)-6-(tert-butoxycarbonylamino)-14a-(cyclopropylsulfonylcarbamoyl)-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-2-yl 4-fluoroisoindoline-2-carboxylate as white solid (0.41 g, 51%).
