Reaction Steps
34 ml of 0.5 N-sodium hydroxide is added to 3.54 g of Z-Ser(But)Ser(But)-Asn-Ala-OMe in 34 ml of methanol. After 3 minutes 17 ml of 1 N-hydrochloric acid is added, the methanol is removed by evaporation for the most part and the product which has separated out is filtered. By crystallization from methanol-ether there is obtained pure Z-Ser(But)-Ser(But)-Asn-Ala-OH of melting point 180°-181°.
