The invention discloses a method for preparing N-(5-carboxyl-2-methylphenyl)-4-(3-pyridine)-2-pyrilamine. The method specifically comprises the following steps: step 1, carrying out ethyl esterification reaction on 3-nitro-4-methyl benzoic acid serving as an initial raw material to generate a compound 2; step 2, reducing nitro of the compound 2 through hydrogenation reduction reaction in the presence of palladium on carbon to generate a compound 3; step 3, reacting the compound 3 with a nitrile amine aqueous solution, and then carrying out base exchange to obtain a compound 4; step 4, carrying out cyclization between the compound 4 and a compound 6 to obtain a compound 7; and step 5, hydrolyzing the compound 7 under the action of an alkaline to generate a compound 8, namely N-(5-carboxyl-2-methylphenyl)-4-(3-pyridine)-2-pyrilamine. The method overcomes the defects that in the prior art such as long reaction time, low yield, high cost, difficulty for industrial production, and the like. A preparation method, which is high in yield, is environmentally-friendly, and is suitable for industrial production, is provided.

A series of pyridin-3-yl pyrimidines was synthesized and evaluated for their Bcr-Abl inhibitory and anticancer activity. The preliminary results indicated that some compounds were promising anticancer agents. Compounds A2, A8, and A9 exhibited potent Bcr-Abl inhibitory activity, suggesting that aniline containing halogen substituents might be important for biological activity. Molecular docking was carried out to investigate the binding mode of them with Bcr-Abl. Details of synthesis and SAR studies of these compounds are described. A series of phenylaminopyrimidines was designed and synthesized as potent Bcr-Abl inhibitors. The screening of these rationally designed compounds for antitumor activity had identified three candidate leads which could be further optimized to improve the anticancer activities.
