To a stirred solution of tert-butyl 2-(2-((3-(phenylmethylsulfonamido)phenyl)amino)oxazol-5-yl)-1H-indole-1-carboxylate 28 (0.24 g, 0.441 mmol) in anhydrous CH2Cl2 (20 mL) was added 1:1 mixture of CH2Cl2:Trifluoroacetic acid (10 mL) at room temperature. Reaction was stirred for 1.5 hour at ambient temperature. It was quenched with aq. saturated NaHCO3 and CH2Cl2 layer was separated. After evaporation of solvent, crude product was purified using MPLC silica column (Biotage) (Acetone/hexane as an eluent) to obtain N-(3-((5-(1H-indol-2-yl)oxazol-2-yl)amino)phenyl)-1-phenyl methane sulfonamide 29 (0.14 g, 71% yield).
