Reaction Steps
3.97 g of Z-Asn-Lys(BOC)-Phe-His-OMe are dissolved in 20 ml of boiling methanol. 2.5 ml of hydrazine hydrate are added to the solution whilst it is still at about 30° C. and the mixture is allowed to stand for 20 hours at room temperature. The peptide-hydrazide is precipitated by adding water, filtered off and washed with water until free of hydrazine. The product is reprecipitated from dimethylformamide-water.
