Pyrimidine plays a significant role among other heterocycles. From the literature survey, in recent years the design of 3,4-dihydropyrimidin-2(1H)-ones nucleus have been attracted for considerable interest because of their therapeutic and pharmacological properties. Pyrimidine nucleus was synthesized by Biginelli reaction. This product was subjected for alkaline ester hydrolysis and these derivatives on treatment with thionyl chloride and substitution by different secondary amines produced final desired compounds. The remaining compounds have been synthesized by above method. The purity of the compounds has been checked by TLC monitoring and the conformation of structure was confirmed by different spectra like UV, IR, NMR, Mass etc. The in-vitro antihypertensive and calcium channel blocking activity have been done by IC50 measurement method with nifedipine as standard.
