Zusammenfassung: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. La presente invención se refiere a un método mejorado para preparar clorhidrato de 1-(4-(4-(3,4-dicloro-2- fluorofenilamino)-7-metoxiquinazolin-6-iloxi)piperidin-1-il)-prop -2-en-1-ona, que inhibe en forma selectiva y eficaz el crecimiento de las células cancerosas inducidas por la sobreexpresión de un receptor del factor de crecimiento epidérmico (EGFR) y previne el desarrollo de resistencia a fármacos causado por la mutación de una tirosina quinasa, y los intermediarios usados en el mismo.
