摘要: The present invention discloses a new anti-lung cancer medicine, and specifically relates to a 2-(2,4,5-substituted phenylamino)pyrimidine derivative I and a crystal form B thereof, belonging to the field of medicinal chemistry. The derivative has the following structure: (1). According to the results of pharmacokinetic and pharmacodynamic research, doxitinib significantly reduces the production of a metabolic product N-Me with a greater toxicity, and maintains or improves the efficacy in comparison to osimertinib. Doxitinib is expected to be developed as a safer and more effective novel medicine for the treatment of non-small cell lung cancer with EGFR mutation in comparison to osimertinib.
