Methods Starting from 2-chloro-4-nitrophenol and 2- pyridine hydrochlorid, 3-chloro-4-(pyridin-2-ylmethoxy) aniline was obtained via etherization and reduction. The obtained aniline coupled with N-(4-chloro-3-cyano-7-ethoxyquinolin-6-yl) acetamide to give 4-[3-chloro-4-(2-pyridylmethoxy) phenylamino]-3-cyano-7-ethoxy-6-N-acetylaminoquinoline. And then it was deacetylated, followed by reacting with4- but-2-enoyl chloride to yield the target compound neratinib.
