Procedure
A mix of [3-(1-Benzenesulfonyl-1H-pyrrolo[2,3-b]pyridin-3-yl)-5-({[1-(3,4-difluoro-benzyl)-2-oxo-1,2-dihydro-pyridine-3-carbonyl]-amino}-methyl)-phenoxy]-acetic acid tert-butyl ester (20 mg, 0.00003 mol) and Trifluoroacetic Acid (20 mg, 0.0001 mol;) in Methylene chloride (8 mL, 0.1 mol) was stirred for overnight. LC-MS showed only formation of the des-phSO2 and saponified product C (1.24 min, ES+/545.64). Evaporated off the solvents and dissolved in DMSO and water and purified on Gilson HPLC to give the desired product (6 mg, 40%) MS (ES+) m/z 545.64 (M+1). 1H NMR (DMSO, 400 MHz): δ 8.41 (dd, 1H), 8.26 (d, 2H), 8.24 (dd, 1H), 7.88 (s, 2H), 7.45-7.35 (m, 2H), 7.30 (s, 2H), 7.18 (m, 1H), 7.10-7.07 (m, 2H), 6.77 (s, 2H), 6.60 (t, 1H), 5.22 (s, 2H), 4.75 (s, 2H), 4.55 (d, 2H),
