There is provided a process for the preparation of 7-substituted-3-quinolinecarbonitriles and intermediates useful in a process to prepare 7-substituted-3-quinolinecarbonitriles and pharmaceutically acceptable salts is described. Where 7-fluoro-4-oxo-1,4-dihydro-3-quinolinecarbonitrile is converted in three steps to 7-substituted-3-quinolinecarbonitriles which inhibit the action of certain protein kinases and are useful in the treatment of cancer.
提供了一种制备7-取代-3-喹啉羰基腈和中间体的方法,该中间体在制备7-取代-3-喹啉羰基腈和药用可接受盐的过程中有用。将7-氟-4-氧代-1,4-二氢-3-喹啉羰基腈转化为7-取代-3-喹啉羰基腈,经过三个步骤,这些化合物抑制某些蛋白激酶的作用,并在癌症治疗中有用。
