Embodiment 1

[0269] Synthesis of Compound 1 (No. ZLT-03-14)

[0270]

[0271] Paclitaxel (1mmol, 853mg) was dissolved in 10mL of dichloromethane, and 1.05 equivalents, 110μL of N-methylmorpholine and 160mg of benzyl propiolate were added at room temperature. After 4 hours of reaction at room temperature, LC-Ms detected that the reaction was complete. Purified by chromatography to obtain 912 mg of intermediate 1-2a (white solid powder), yield: 90%.

[0272] Dissolve 507mg of intermediate 1-2a in 10mL of ethyl acetate, add 507mg of Pd / C, and react at 50°C under an atmosphere of hydrogen. The progress of the reaction was monitored by LC-Ms. After the reaction was complete, Pd / C was filtered, and the filter cake was washed twice with ethyl acetate. The filtrates were combined and concentrated to obtain 460 mg of intermediate 1-3a (white solid powder), with a yield of 99%. It was directly used in subsequent reactions without further purification.
