참여 물질

반응 단계

To a solution of ((R)-1-methyl-3-oxo-3-pyrrolidin-1-yl-propyl)-carbamic acid tert-butyl ester (crude from step 1, 189 mg, 0.74 mmol) in CH2Cl2 (5 mL) was added trifluoroacetic acid (2.0 mL, 27.0 mmol). The reaction mixture was stirred at room temperature for 2 h then concentrated to give (R)-3-amino-1-pyrrolidin-1-yl-butan-1-one trifluoroacetate as a pale yellow oil which was used without further purification.
