Procedure

A solution of {1-(1-acetyl-1H-indol-3-yl)-2-[(2S,4R)-2-(3-chloro-2-fluoro-benzylcarbamoyl)-4-fluoro-pyrrolidin-1-yl]-2-oxo-ethyl}-carbamic acid tert-butyl ester (102 mg, 0.173 mmol) and TFA (66.7 μL, 0.866 mmol) in CH2Cl2 (0.58 mL) was stirred at 23° C. overnight. TFA (66.7 μL, 0.866 mmol) was again added and the reaction mixture was stirred at 23° C. for an additional 4 h to complete the reaction. Solvents were removed in vacuo and the crude residue was purified by preparative HPLC (Waters SunFire C180 DB, 5 μm, 19×50, eluent: 5% CH3CN/95% H2O to 100% CH3CN in 17 min, CH3CN and H2O containing 0.1% of TFA, flow 20 mL/min) to give after lyophilization of the purified fractions the desired material. MS (LC-MS): 487.1 [M−H]−; tR (HPLC conditions b): 3.19 min.
