Trifluoroacetic acid → HCID 69074486, compound

Participants

Reaction Steps

The solution of tert-butyl (2S)-phenyl[({[4-(4-pyridinyl)phenyl]amino}carbonyl)amino]acetate (50.0 mg) in dichloromethane (1.0 mL) and trifluoroacetic acid (954 μL) was stand at ambient temperature for 2 hours. The resulting mixture was concentrated in vacuo and the residue was diluted with chloroform (2 mL), then concentrated. To the residue was added ethyl acetate (2.0 mL) and the precipitated solid was collected by filtration, then washed with ethyl acetate (2.0 mL) to give (2S)-phenyl[({[4-(4-pyridinyl)phenyl]amino}carbonyl)amino]acetic acid trifluoroacetate (39 mg) as off-white crystals.
