実験手順

A solution of ((S)-1-Cyclohexyl-2-{(S)-2-[2-(2,3-dihydro-indol-1-yl)-pyridin-4-yl]-pyrrolidin-1-yl}-2-oxo-ethyl)-carbamic acid tert-butyl ester (120 mg, 0.24 mmol) in DCM (5 mL) is added TFA (6 mL). After stirring at room temperature for 1 h, the reaction mixture is concentrated down to give crude (S)-2-Amino-2-cyclohexyl-1-{(S)-2-[2-(2,3-dihydro-indol-1-yl)-pyridin-4-yl]-pyrrolidin-1-yl}-ethanone, which is used in next step without further purification.
