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 1N 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]+.
