Synthesis, characterization and antimicrobial activity of pyrazole-pyrimidone clubbed derivatives

4-(2-(1-(4-aryl-3-(furan-2-yl(hydroxy)methyl)-6-methyl-2-oxo-1,2,3,4-tetrahydropyrimidine-5-carbonyl)-3-methyl5-oxo-1H-pyrazol-4(5H)-ylidene)hydrazinyl)-N-(thiazol-2-yl) benzene sulphonamides (2a-e) were synthesised by condensation of 4-(2-(1-(4-aryl-6-methyl-2-oxo-1,2,3,4-tetrahydropyrimidine-5-carbonyl)-3-methyl-5-oxo-1Hpyrazol-4(5H)-ylidene) hydrazinyl)-N-(thiazol-2-yl) benzene sulphonamide (1a-e) with furfuraldehyde. The structures of all the compounds (2a-e) were characterized duly. The compounds were also monitored for antimicrobial activity.
