Reaction Steps

To a solution of (S)-2-[3-(2-amino-1-methylethyl)-7-bromo-2-(3,5-dimethylphenyl)-1H-indol-5-yl]-2-methylpropionic acid ethyl ester (79 mg in 1 mL methanol) was added 8 mg of 10% palladium on carbon catalyst. The reaction flask was fitted with a hydrogen balloon, evacuated and recharged with hydrogen (3 times) and stirred at room temperature. After 7 hours the reaction was flushed with nitrogen, filtered over diatomaceous earth, concentrated in vacuo and purified by flash chromatography on silica gel (chloroform:methanol, 92:8) to provide the title compound (68 mg).
