Trifluoroacetic acid → HCID 20779513, compound

Participants

Reaction Steps

A methanol solution containing trifluoroacetic acid (40%, 6 ml) was added to the tris[4-[β-t-butoxycarbonyl-N-[2-(1H-indol-3-yl)acetyl]-L-alanyl]aminophenyl]methane (50 mg) at room temperature, and the mixture was stirred at room temperature for 2 hours. The reaction solution was concentrated under reduced pressure, and a portion of the residue was purified by preparative high performance liquid chromatography using methanol/trifluoroacetic acid (100/0.1) and water/trifluoroacetic acid (100/0.1) as a mixed eluent, to obtain 1.3 mg of the title compound.
