Abstract
A new series of pyrimidine -2-thione derivatives were synthesized via two routes and designated as antifolate. The heterocyclic ring was prepared by direct reaction of benzoyl acetone with thiosemicarbiazide in acidic medium. Also, the pyrimidine-2-thione ring reacts with p-aminobenzoic acid to form 4-amino-N-(4-methyl-6-phenyl)-2-thioxypyrimidine 1[2H] –yl benzamide. The second route synthesis 5-[{4-methyl-6-phenyl-2-thioxo pyridine-1-yl amino}-4-(4-methyl phenylsulfonamido)-5-oxobenzoyl] pentanoic acid. All structures were elucidate by their physical & spectroscopic data FTIR, 1H &13C NMR.
