Reaction Steps

3.14 g of the dihydrochloride of Z-Phe-His-Leu-Val-Ile-His-NH2 from Example 1 are hydrogenated for 4 hours at normal pressure in 100 ml of water/methanol (5:95) in the presence of 350 mg of palladium-on-carbon (5%). After removing the catalyst by filtration, evaporating off the solvent and drying in a high vacuum, H-Phe-His-Leu-Val-Ile-His-NH2.2HCl is obtained in the form of a colourless powder. Rf (B11)=0.26.
