Procedure

Ethyl 3-[4-({2-[1-benzhydryl-5-chloro-2-(2-{[(3,4-dichlorobenzyl)sulfonyl]amino)-ethyl)-1H-indol-3-yl]ethyl}sulfonyl)phenyl]-2,2-dimethylpropanoate (0.04 g, 0.05 mmol), THF (0.5 mL), MeOH (0.5 mL), and 1N NaOH (0.5 mL) were stirred together overnight. Solvents were removed and the resulting residue was taken up in water. The solution was acidified with 1N HCl and extracted with ethyl acetate. The extract was dried over sodium sulfate, and evaporated. The resulting residue was triturated with a mixture of ether and hexanes to give 0.04 g of 3-[4-({2-[1-benzhydryl-5-chloro-2-(2-{[(3,4-dichlorobenzyl)-sulfonyl]amino}ethyl)-1H-indol-3-yl]ethyl}sulfonyl)phenyl]-2,2-dimethylpropanoic acid as a white solid; mp 207-208° C.; MS (ESI) m/z 849.1 (M−H); HRMS: calcd for C43H41Cl3N2O6S2, 850.1472; found (ESI+), 851.1545.
