실험 절차
3.01 g of atosiban acetate is prepared by dissolving the linear atosiban obtained from Example 2 in 250 ml of 10% acetonitrile aqueous solution, adjusting the pH value to 8 to 9 with 30% ammonia water, adding 0.85 g of H2O2, reacting for 30 min at 25° C., monitoring with HPLC (HPLC: 89.5%), filtering after reaction, purifying filtrate by preparative RP-HPLC (column C18 or C8), transferring salt, and freeze-drying, MS: 994.5, HPLC: 99.6%.
