실험 절차

A solution cooled on an ice bath of 5.14 g of TFA, H-Phe-Thr-Asn-Ser-OMe (8.78 mM) in 100 ml of DMF has 3.17 g of Boc-Ile-OSu (9.66 mM), 1.30 g of HOBt (9.62 mM) and N-ethyl morpholine added thereto until a pH of 7 is obtained. After 20 hours of reaction at ambient temperature, the solution is concentrated under reduced pressure and the residue taken up in ether gives a precipitate which is filtered and dried in vacuo. 5.24 g of product are obtained.
