Procedure

To 14-tert-butoxycarbonylamino-18-(4-fluoro-1,3-dihydro-isoindole-2-carbonyloxy)-2,15-dioxo-3,16-diaza-tricyclo[14.3.0.04,6]nonadecane-4-carboxylic acid methyl ester (319 mg, 0.49 mmol) in a 1:1:1 mixture of THF:MeOH:H2O (6 mL) was added lithium hydroxide (104 mg, 2.47 mmol). The resulting slurry was stirred at room temperature overnight then diluted with EtOAc and washed with 1 N HCl and brine. The resulting organic layer was dried over sodium sulfate and concentrated to provide the crude 14-tert-butoxycarbonylamino-18-(4-fluoro-1,3-dihydro-isoindole-2-carbonyloxy)-2,15-dioxo-3,16-diaza-tricyclo[14.3.0.04,6]nonadecane-4-carboxylic acid (300 mg, 97% yield). LCMS found 630.8 [M+H]+.
