Reaction Steps

To a solution of {(S)-1-cyclohexyl-2-oxo-2-[(S)-2-(3-phenoxy-phenyl)-pyrrolidine-1-yl]-ethyl}-carbamic acid tert-butyl ester in CH2Cl2 (20 mL) is added TFA (10 mL) and the mixture is stirred for 30 minutes. The mixture is concentrated under reduced pressures to give (S)-2-amino-2-cyclohexyl-1-[(S)-2-(3-phenoxy-phenyl)-pyrrolidin-1-yl]-ethanone as a TFA salt quantitatively (1.65 g). LCMS m/z 379 (M+1).
