Embodiment 7

[0054] Embodiment 7 is a comparative example for preparing the compound shown in formula 5. In this example, the inventor adjusted the reaction molar ratio of the compound shown in formula 3 to the compound shown in formula 4 to be 1:1.6, and adjusted the compound shown in formula 3 The reaction time with the compound shown in formula 4 is 5 hours, and on its technical effect, the product yield that the present embodiment obtains is 1:(1.05~ 1.4), and the reaction time of the compound shown in formula 3 and the compound shown in formula 4 contact stirring is the product yield when 2~3 hours, does not obtain obvious improvement, therefore, from the point of view of material consumption and energy consumption, the present invention The molar ratio of the compound shown in the formula 3 and the compound shown in the formula 4 in the step (2) is 1: (1.05~1.4), and the reaction time of the compound shown in the formula 3 and the compound shown in the formula 4 is 2~3 hours, thus no...

Embodiment 11

[0064] Example 11 is a comparative example for preparing the compound shown in formula 7. In this example, the inventor adjusted the reaction molar ratio of the compound shown in formula 5 to the compound shown in formula 6 to be 1:1.6, and adjusted the compound shown in formula 5 The reaction time with the compound shown in formula 6 is 4 hours, and on its technical effect, the product yield that the present embodiment obtains is 1:(1.0~ 1.3), and the product yield when the compound shown in formula 5 and the compound shown in formula 6 are contacted and stirred for 1 hour 45 minutes~2.5 hours, the product yield has not been improved, on the contrary the product yield has decreased, in addition, obtained The HPLC purity of the compound shown in formula 7 was significantly reduced from 99.7% to 98.2%, resulting in increased product impurities. Therefore, from the perspective of material consumption and energy consumption, the molar ratio of the compound shown in formula 5 and ...

Abstract

The invention relates to a synthesis process of a VEGFR (vascular endothelial growth factor receptor) inhibitor tevozanib. According to the invention, commercially available raw materials are subjected to a halogenation reaction, an esterification reaction and an addition reaction to synthesize a target product. Generally speaking, according to the synthetic route and the synthetic process, the synthetic steps are simplified, the reaction yield of each step is high, the treatment after the reaction is simple, pulping purification is mostly adopted for purification, the use of column chromatography is avoided, the operation process is simple and cheap, and the synthetic route and the synthetic process are favorably applied to industrial mass production.

Description

technical field [0001] The invention relates to the technical field of biomedicine, in particular to a synthesis process of a VEGFR inhibitor tivozanib. Background technique [0002] Tivozanib (trade name Fotivda) is a tyrosine kinase inhibitor. In vitro cellular kinase assays demonstrated that tivozanib inhibited the phosphorylation of vascular endothelial growth factor receptor (VEGFR)-1, VEGFR-2, and VEGFR-3 at clinically relevant concentrations and inhibited other kinases, including c-kit and PDGFRβ, as well as tumor growth in various tumor cell types, including human renal cell carcinoma. [0003] Tivozani was originally discovered by Kyowa Hakko Kirin in Japan, and was first approved in the European Union for the treatment of advanced renal cell carcinoma (RCC) in August 2017. On March 10, 2021, the U.S. FDA approved AVEO PHARMS' tivozanib capsules for the treatment of adults with relapsed or refractory advanced renal cell carcinoma after two or more prior systemic t...
