摘要
4-(4-氨基苯基)-3-吗啉酮是合成利伐沙班的一个重要中间体,以吗啉酮为原料,利用Buchwald-Hartwig偶联反应制得4-苯基-3-吗啉酮,再经硝化,还原三步反应制备4-(4-氨基苯基)-3-吗啉酮。
4-(4-amino-phenyl)-3-morpholinone as the key mtermecllate in the Syntnesls rivaroxaban, 4-phenyl-3-morpholinone was prepared by. the raw material morpholinone using the Buchwald-Hartwig coupling reaction, and then via nitration,reduction three-step reaction was obtained 4- (4-amino-phenyl) - 3-morpholinone.
