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.

The synthesis of 4,5,7-trichloroquinoline makes use of ethyl orthoformate, cyanoacetic ester and 3,5-dichloroaniline as the raw materials. The synthesis is completed by four steps: condensation, cyclization, hydrolyzation and chlorination. Several conditions concerned in the process are studied, the whole yield of 4,5,7-trichloroquinoline is about 53%, and the purity of it is about 96%. All the products are testified by IR, NMR and HPLC.
