专利号:WO-2025102245-A1 优先权日:2023-11-14 标题:Synthesis method for dual endothelin receptor antagonist aprocitentan 发明人:XU XIANGUANG; WANG ZHEN; ZHU GUORONG; TU YONGJUN 权利人:ZHEJIANG TIANYU PHARMACEUTICAL CO LTD 摘要:Provided in the present invention is a synthesis method for aprocitentan, comprising the following steps: 1) a compound of formula X and a sulfonylation reagent compound of formula XI undergoing a sulfonylation reaction to prepare a compound of formula XII; and 2) removing an R protective group on the pyrimidine sulfonamide compound of formula XII obtained in the previous step, so as to obtain aprocitentan. The synthesis method of the present invention overcomes the problem in the prior art that preparing macitentan by means of condensation of chloropyrimidine and sulfonamide needs to use an excessive amount of a strong base and involves a relatively low conversion efficiency, relatively many side products and other defects. The synthesis method does not need using a fluorine reagent for fluorination, involves economical steps, is environmentally-friendly, and has a relatively low comprehensive production cost. Compared with existing methods for preparing aprocitentan, the method of the present invention has characteristics of easily available raw materials, being environmentally-friendly and economical, and the like, thereby facilitating the industrial production of aprocitentan.

Adding THF solution containing compound II and 5-bromo-2-chloropyrimidine slowly into THF solution containing base to react, or adding THF solution containing compound II and THF solution containing 5-bromo-2-chloropyrimidine slowly at the same time into THF solution containing base to react and obtain Macitentan (shown as compound I), wherein the base is selected from sodium hydride, potassium hydride, lithium hydride or lithium bis(trimethylsilyl)amide. The selectivity of the preparation method is very good, which is suitable for industrial production. The obtained product Macitentan has good quality and high yield. And the product compound II also has good quality and high yield, its HPLC purity is up to 99.0%, the content of impurity A is less than 0.20%, the content of impurity B is less than 0.25%.
