Abstract

The invention provides a pharmaceutical composition of a 2-aminopyrimidine compound or a pharmaceutically acceptable salt thereof. In particular, the invention provides a pharmaceutical composition containing N-((5-((5-chloro-4-((naphthalene-2-yl)amino))pyrimidine-2-yl)amino)-2-((N-methyl-N-dimethylaminoethyl)amino)-4-methoxyphenyl) acrylamide or a pharmaceutically acceptable salt thereof, and a method for preparing the above pharmaceutical composition.

Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations, in particular, the invention relates to compound N-((5-((5-chloro-4-((naphthalene-2-yl)amino))pyrimidin-2-yl)amino)-2 -((N-methyl-N-dimethylaminoethyl)amino)-4-methoxyphenyl)acrylamide or its pharmaceutically acceptable salt pharmaceutical composition, and preparation of the pharmaceutical composition method. Background technique [0002] Epidermal growth factor receptor (EGFR), a receptor tyrosine protein kinase, regulates cell proliferation, survival, adhesion, migration and differentiation. EGFR is overactivated or continuously activated in a variety of tumor cells, such as lung cancer, breast cancer, and prostate cancer. Blocking the activation of EGFR and Erb-B2 has been clinically validated as the leading approach to target therapy of tumor cells. Two small-molecule inhibitors targeting EGFR, gefitinib and erlotinib, received fast-track approval from the U.S. Food and Drug Admi...
