Our effort toward the process improvement of anaplastic lymphoma kinase (ALK) inhibitor ASP3026 (1) is described. A cost-effective and practical synthesis of 1 was accomplished as a result of the change of starting material from 2,4-dichloro-1,3,5-triazine (6) to cyanuric chloride (9) and late-stage introduction of a highly reactive N-methyl piperazine moiety by reductive amination of intermediate ketone 13. The modified process avoided the challenges with the original synthesis and furnished the several hundred kilograms of high-quality API with high economic efficiency, operability, and reproducibility. Furthermore, a sequence of investigation of polymorphic control in the second-generation synthetic route to obtain the thermodynamically desired, most stable polymorph Form A04 is also discussed.

Anaplastic lymphoma kinase (ALK) is a validated therapeutic target for treating echinoderm microtubule- associated protein-like 4 (EML4)-ALK positive non-small cell lung cancer (NSCLC). We synthesized a series of 1,3,5-triazine derivatives and identified ASP3026 (14a) as a potent and selective ALK inhibitor. In mice xenografted with NCI-H2228 cells expressing EML4-ALK, once-daily oral administration of 14a demonstrated dose-dependent antitumor activity. Here, syntheses and structure-activity relationship (SAR) studies of 1,3,5-triazine derivatives are described.

Paragraph 0187; 0188; 0189, (2017/01/02)
The invention belongs to the technical field of medicines, and particularly relates to a triazine derivative anaplastic lymphoma kinase inhibitor shown in a general formula (I), pharmaceutically acceptable salt, ester, solvate or stereoisomer of the inhibitor. R1, R2, R3, R4, R6, R7 and A rings are defined in the description. The invention further relates to a preparation method of compounds, a medicinal preparation containing the compounds, a medicine combination containing the compounds and an application of the compounds, the pharmaceutically acceptable salt, ester, solvate or stereoisomer to preparation of a medicine for treating and/or preventing anaplastic lymphoma kinase-mediated cancer-related diseases.
