According to the Box-Benhnken design principle,the method of response surface method with 3 factors and 3 levels was used. The factors influencing the technological parameters were determined by means of regression analysis. Response surfaces were finally graphed with the yield as the response value. The synthesis conditions were optimized as follows:reaction reagent was NBS,stoichiometric proportion between NBS and anhydrovinblastine was 1.07; the dosage of TFA was 22 mL/L; reaction temperature was -68 ℃ and duration was 90 min.
