MÉTODO DE PREPARAÇÃO DE CLORIDRATO DE 1-(4-(4-(3,4-DICLORO-2-FLUOROFENILAMINO)-7-METOXIQUINAZOLIN-6-ILOXI)PIPERIDIN-1-IL)-PROP-2-EN-1-ONA E INTERMEDIÁRIOS UTILIZADOS NO MESMO
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, 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.
