Procedure

To a solution of 1,1-dimethylethyl (1S,4S,6S)-4-({[5-(trifluoromethyl)-2-pyrazinyl]amino}methyl)-3-azabicyclo[4.1.0]heptane-3-carboxylate D30 (100 mg) in DCM (4 ml) TFA (2 ml, 26.0 mmol) was added dropwise. The mixture was left reacting at room temperature for 2 hours. Solvent was evaporated in vacuum and the crude was purified by SCX chromatography using MeOH 100% to MeOH/NH3 2M. It was recovered the title compound D31 (57 mg). UPLC: (Acid Final_QC): rt=0.48 minutes, peaks observed: 273 (M+1).
