Reaction Steps

The tris[4-[O-benzyl-N-[2-(1H-indol-3-yl)acetyl]-L-tyrosyl]aminophenyl]methane (70 mg) obtained in Example 92 was dissolved in a mixed solvent of methanol (4 ml) and N,N-dimethylformamide (4 ml), 10% palladium carbon (25 mg) was added, and then the mixture was stirred for 3 days at room temperature under a hydrogen atmosphere. The reaction mixture was filtered, and the filtrate was concentrated under reduced pressure. 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 2.4 mg of the title compound.
