Problems solved by technology

However, patients who respond to crizotinib often develop resistance to the drug within 1 year of taking it
In recent years, the US FDA has approved a series of ALK inhibitor drugs to treat patients with resistance to crizotinib. However, after a period of medication, patients still develop drug resistance

Abstract

The invention discloses a pyrimidine derivative with ALK inhibitory activity, a synthesis method and applications thereof. The method comprises the following steps: reacting a 4-aminopiperidine compound with halogenated aromatic hydrocarbon to obtain a secondary amine product, obtaining a BOC-removed piperidine compound under the action of trifluoroacetic acid, and reacting the BOC-removed piperidine compound with 2,5-dichloro-N-(2-(isopropylsulfonyl)phenyl)pyrimidine-4-amine. The preparation method has the advantages that the preparation process is simple and easy to operate. The prepared product has ALK inhibitory activity and can be used for preparing an ALK inhibitor.

Description

technical field [0001] The invention belongs to the field of medicinal chemistry, and more specifically relates to a structure of a pyrimidine derivative with ALK inhibitory activity and a preparation method thereof. Background technique [0002] Lung cancer is one of the most common malignant tumors in the world, and its mortality rate ranks first among all malignant tumors. Lung cancer can be divided into non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC), of which 85% belong to non-small cell lung cancer. Most non-small cell lung cancer patients are already in the middle and advanced stages when they are diagnosed, and the 5-year survival rate is very low. With the deepening of scientific research, scientists have discovered that the anaplastic lymphoma kinase (ALK) fusion gene is one of the key genes driving non-small cell lung cancer. [0003] At present, molecular targeted therapy is the most effective and most widely used treatment method among man...
