Reaction Steps

Z-D-Trp-NH2 (3 g; 8.9 mmol; 1 eq.) was dissolved in DMF (100 ml). HCl 36% (845 μl; 1.1 eq.), water (2 ml) and palladium on activated charcoal (95 mg, 0.1 eq.) were added to the stirred mixture. The solution was bubbled under hydrogen for 24 hr. When the reaction went to completion, the palladium was filtered on celite. The solvent was removed in vacuo to afford HCl, H-D-Trp-NH2 as a colorless oil.
