Trifluoroacetic acid → 4-(2-Aminoethyl)benzonitrile

Participants

Reaction Steps

1.90 g commercially available [2-(4-Cyano-phenyl)-ethyl]-carbamic acid tert-butyl ester were dissolved in 100 ml dichloromethane. 10 ml trifluoroacetic acid were added and the reaction mixture was stirred at room temperature for one hour. 250 ml ethyl acetate were added and the mixture was washed three times with saturated NaHCO3 solution. The organic layer was dried over MgSO4 and then the solvent was removed in vacuo to obtain 700 mg 4-(2-Amino-ethyl)-benzonitrile as pale yellow solid.
