The invention relates to a preparation method of an HIF-2alpha small-molecule inhibitor (2-((benzyl(furan-2-yl methyl) amino) methyl)-8-methyl-4H-pyrido[1, 2-a]pyrimidine-4-ketone). The compound is characterized in that 4-methylpyridine-2-amine is used as an initial raw material, and 2-chloro-8-methyl-4H-pyrido [1, 2-a] pyrimidine-4-ketone is obtained through condensation cyclization of 4-methylpyridine-2-amine and the compound, furfural is taken as an initial raw material, an addition reaction is carried out on the furfural and benzylamine to obtain N-furan benzylamine, and a N-alkylation reaction is carried out on the obtained 2-chloro-8-methyl-4H-pyrido[1, 2-a]pyrimidine-4-ketone and N-furan benzylamine to obtain the HIF-2alpha small-molecule inhibitor. The invention discloses the preparation method of the HIF-2alpha small-molecule inhibitor for the first time, the method has the advantages of few steps, simple operation, rapid reaction and no need of high pressure, the yield and purity of the prepared compound are high, and the raw materials are easy to obtain.

We herein disclose a series of novel diaryl urea derivatives possessing a 4H-pyrido[1,2-a]pyrimidin-4-one group as novel potent anticancer compounds. The structures were confirmed by IR, 1H-NMR, and MS. All the compounds were screened for their antiprofilerative activity agaist the human breast cancer cell line (MDA-MB-231). The pharmacological results indicated that most of the compounds showed moderate activity. The best of this series is compound 4c (IC50 = 0.7 μmol/L), with a potency 3.6-fold higher than Sorafenib (IC50 = 2.5 μmol/L), which was approved in 2005.
Synthesis of some substituted pyrido[1,2-a]pyrimidin-4-ones and 1,8-naphthyridines

The substituted 4H-pyrido[1,2-a]pyrimidin-4-ones (I) were obtained by the condensation of substituted 2-aminopyridines with β-ketocarboxylic esters in PPA. Some of the derivatives I were transformed into the corresponding 1,8-naphthyridines II and III.
