Procedure

A solution of (3R,6R)-3-(2-benzyloxycarbonylethyl)-6-(1-methylindol-3-ylmethyl)piperazine-2,5-dione (1.50 g) in ethanol (300 ml) containing 10% paradium on charcoal (0.75 g) was hydrogenated at ambient temperature and atmospheric pressure. After catalyst was filtered off and solvent was evaporated, crude solid was recrystallized from ethanol and dried in vacuo to give (3R,6R)-3-(2-carboxyethyl)-6-(1-methylindol-3-ylmethyl)piperazine-2,5-dione (0.58 g).
