Reaction Steps

A solution of {(S)-2-[(S)-2-(2-benzoimidazol-1-yl-pyridin-4-yl)-pyrrolidin-1-yl]-1-cyclohexyl-2-oxo-ethyl}-carbamic acid tert-butyl ester (70 mg, 0.14 mmol) in DCM (2 mL) is added TFA (2 mL). After stirring at room temperature for 1 h, the reaction mixture is concentrated down to give crude (S)-2-Amino-1-[(S)-2-(2-benzoimidazol-1-yl-pyridin-4-yl)-pyrrolidin-1-yl]-2-cyclohexyl-ethanone, which is used in next step without further purification.
