Reaction Steps
A solution of (αR,βR)-Nα -Benzyloxycarbonyl-5-chloro-1-ethyl-β-methyltryptophan methyl ester (4.17 g) in methanol (100 ml) containing 10% paradium on charcoal (0.5 g) was hydrogenated. After removal of the catalyst and evaporation of the solvent, (αR,βR)-5-chloro-1-ethyl-β-methyltryptophan methyl ester (2.45 g) was obtained as a yellow amorphous powder.
