１−（４−（４−（３，４−ジクロロ−２−フルオロフェニルアミノ）−７−メトキシキナゾリン−６−イルオキシ）ピペリジン−１−イル）−プロパ−２−エン−１−オン塩酸塩の製造方法および該方法で用いられる中間体

摘要

The present invention relates to an improved method for preparing 1-(4-(4-(3,4-dichloro-2-fluorophenylamino)-7-methoxyquinazolin-6-yloxy)piperidin-1-yl)-prop-2-en-1-one hydrochloride, which selectively and effectively inhibits the growth of cancer cells induced by over-expression of an epidermal growth factor receptor (EGFR) and prevents the development of drug resistance caused by mutation of a tyrosine kinase, and intermediates used therein.
