Procedure

Methyl 4-({2-[1-benzhydryl-5-chloro-2-(2-{[(2,6-difluorobenzyl)sulfonyl]amino}ethyl)-1H-indol-3-yl]ethyl}sulfonyl)benzoate (1 eq), THF (0.1M), MeOH (1 mL/1 mL THF), and NaOH (1N) (11 eq) were stirred together overnight. Solvents were removed and the resulting residue was taken up in water. The solution was acidified with 1N HCl and collected resulting precipitate by filtration. Obtained 4-({2-[1-benzhydryl-5-chloro-2-(2-{[(2,6-difluorobenzyl)sulfonyl]amino}ethyl)-1H-indol-3-yl]ethyl}sulfonyl)benzoic acid (white-yellow solid) in 96% yield. HRMS calc for [C39H33ClF2N2O6S2—H] 761.13638 found 761.13565.
