Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps,and cheap raw materials. 152460-09-8, name is N-(2-Methyl-5-nitrophenyl)-4-(pyridin-3-yl)pyrimidin-2-amine. A new synthetic method of this compound is introduced below., HPLC of Formula: C16H13N5O2
Example 4: Preparation of 4-methyl-N-3-(4-pyridin-3-ylpyriinidin-2-vI)benzene-l,3-dianiineTo a solution of (2-methyl-5-nitrophenyl)-(4-pyridin-3-ylpyrimidin-2-yl)amine ( lOOg, 0.32mol) in methanol (600 ml), 10% palladium on carbon (5g, 50% wet) and aqueous hydrazine hydrate (81.45g, 80 %) were added at 25-30 C and reaction mixture was refluxed for 8 hours under inert atmosphere. After completion of reaction, the catalyst was removed by filtration and the solvent was distilled out completely under vacuum. The resulting residue was diluted with demineralized water (400 ml). The precipitated solid was filtered, washed with demineralized water and dried to give 88g (98%) of the title compound having purity 99.8% by HPLC.
