Description

Technical field [0001] The present invention relates to the field of medical technology. It is mainly involved in an aminoprimidine derivative and its hydrolyzatics, isomers, solvates, and pharmaceutical compositions, and the preparation method thereof and the application thereof as a drug. In particular, it is used as an application of anti-cancer drugs mediated by EGFR kinase. Background technique [0002] According to the data released by the World Health Organization, cancer has caused huge disease treatment in a global scale, and my country's cancer new cases and deaths are the first place in the world. Among them, lung cancer as one of the most common malignant tumors has become the first place in the death of malignant tumors in my country. In clinical diagnosis, lung cancer is divided into non-small cell lung cancer (NSCLC) accounted for 80-85% of all lung cancer, and about 75% of patients found in the middle and late stage (III or IV), There is a local advanced or metast...
