Procedure
A mixture of (S)-tert-butyl 4′-((5-(1-(4-bromophenyl)ethylcarbamoyl)-2,3-dimethyl-1H-indol-1-yl)methyl)biphenyl-2-carboxylate (20 mg, 0.03 mmol) in TFA/DCM (1 mL, 30%) was stirred at rt for 2 h. The completion of the reaction was monitored by anal. HPLC. The solvent was removed to obtain the crude which was purified by reverse phase prep-HPLC (MeOH/Acetonitrile/water) to obtain the title compound. ESI-MS (m/z): 581/583 [M+H]+.
