Procedure

To a solution of 1-(1,1-dimethylethyl) 2-methyl (2R,5S)-5-[5-[{2-[3,5-bis(trifluoromethyl)phenyl]-2-methylpropanoyl}(methyl)amino]-4-(4-fluoro-2-methylphenyl)-2-pyridinyl]-2-methyl-1,2-pyrrolidinedicarboxylate (Intermediate 19, 70 mg, 0.095 mmol) in dry Dichloromethane (DCM) (2 ml) was added TFA (0.5 ml, 6.49 mmol) and the reaction mixture was stirred for 2.5 hours at r.t. The solvent and the excess of TFA were evaporated and the residue was purified by SPE-SCX cartridge to afford the title compound (55 mg, 0.086 mmol, 91% yield) as a white solid. UPLC: Rt 0.76 min (broad peak), m/z 640 [M+H]+.

Workup

  1. customThe solvent and the excess of TFA were evaporated
  2. customthe residue was purified by SPE-SCX cartridge
