2,2-di(pyridin-2-yl) hexahydropyrimidine heterocyclic compound was prepared by condensation reaction of 1,3- propanediaminewith di(pyridin-2-yl)methanone 1.5,5-dimethyl-1,3-bis[(methyl sulfonyl)oxy]-2,2-dipyridin-2- ylhexahydropyrimidine 2 was prepared by protection of both N-H groups in 2 using MeSO3Cl reagent in
pyridine/THF media.The prepared compounds revealed good thermal stability, and simple one step decomposition mechanism. The condensation reaction to prepare 1has been monitored by IR.The structures of the desired compounds were characterized by elemental analysis, EI-Ms, UV-Vis, FT-IR, TG and NMR.
