Abstract
Pyrimidine is a heterocyclic aromatic organic compound similar to benzene and pyridine, containing two nitrogen atoms at positions 1 and 3 of the six-member ring. The known 2-benzimidazolyl guanidine was synthesized from substituted o-phenylenediamine and cyano guanidine was treating with triethylorthoformate (CH (OC2H5)3) and active methylene compounds containing carbonyl function 1, 3-diketones to furnish substituted 2-[(1H-benzo[d]imidazol-2-yl) amino]-pyrimidine.
