Synthesis method for anti-tumor compound and intermediate thereof

The present invention belongs to the field of medical technology, and in particular relates to a synthesis method for an anti-tumor compound and an intermediate thereof. The synthesis method of the present invention has enhanced operability and simplified process, obtains the synthesized target compound having high purity without complex recrystallization process, reduces the generation of three wastes, and is more suitable for industrial production. The intermediate provided in the present invention is used for preparing the anti-tumor compound, effectively reducing by-products during the reaction process, improving the overall yield of the reaction which is at least double higher than the existing synthesis method.
