The target compound N'-(5-Cyano-4-(4-fluorophenyl)-1,6-dihydro-1-methyl-6-oxopyrimidin-2-yl)-4-methylbenzohydrazide have been synthesized by the condensation of 4-(4-Fluorophenyl)-2-hydrazinyl-1,6-dihydro-1-methyl-6-oxopyrimidine-5-carbonitrile with different aroylchlorides. The obtained products were characterized by 1H NMR, Mass and IR Spectra.

Condensation of 2-hydrazinyl-1,6-dihydro-1-methyl-6-oxo-4-isobutylpyrimidine-5-carbonitrile (3) with different aromatic aldehyde gave the corresponding 2-(Benzylidinehydrazinyl)-1,6-dihydro-6-oxo-4-isobutylpyrimidine-5-carbonitrile (4). The reaction between 1,6-dihydro-1-methyl-2-(methylthio)-6-oxo-4-isobutylpyrimidine-5-carbonitrile (2) with hydrazine hydrate furnished (3). The condensation of 1,2,3,4-tetrahydro-4-oxo-6-isobutyl-2-thioxopyrimidine-5-carbonitrile (1) with methyl iodide yielded 2. Finally the products were characterized by 1H NMR, Mass and IR Spectra.
