Synthesis and Characterization of some Benzylidinehydrazinyl Derivatives of Newer Pyrimidine-5-Carbonitrile Moiety
View through CrossRef
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.
