Publication number: 20230212167Abstract: The present invention belongs to the technical field of medicines, and particularly relates to a method for synthesizing an anti-tumor compound and intermediates thereof. The synthesis method of the present invention has improved operability and allows for a simplified process, in which higher purity can be achieved without the complicated process of recrystallizing the synthesized target compound, and thus less of the three wastes is produced, making the method more suitable for industrial mass production. Where the intermediates according to the present invention are used for preparing an anti-tumor compound, by-products are effectively reduced during reactions, and thus the overall yield of the reactions are improved, and is at least twice as high as that obtained using the existing synthesis method.Type: ApplicationFiled: May 8, 2021Publication date: July 6, 2023Applicant: Transthera Sciences (Nanjing), Inc.Inventors: Lin LI, Sishun KANG, Zhonghui WAN
