Participants

Reaction Steps

To a solution of ((S)-1-benzylcarbamoyl-ethyl)-carbamic acid tert-butyl ester (180 mg, 0.645 mmol) in dichloromethane (1.0 mL) was added trifluoroacetic acid (0.500 mL, 6.73 mmol). The reaction mixture was stirred for 4 h. The reaction mixture was then concentrated in vacuo to afford (S)-1-benzylcarbamoyl-ethyl-ammonium trifluoro-acetate, m/z 179.2 [M+1]+.
