Synthesis, Characterization and Evaluation of Anti-Microbial Activity of Some Novel 1,2,4-Triazoles.

Some novel 4-(aryliidineamino)-5-(1-(4-isobutylphenyl) ethyl)-4-yl-4H-1,2,4-triazole-3-thiols were prepared from the  reaction of carbon-di-sulphide and hydrazine hydrate in water to produce thiocarbohydrazides. The thiocarbohydrazides is then refluxed with ibuprofen for 2 hour, followed by cooling to room temperature and washing with sodium bicarbonate solution to produce  5-(1-(4-isobutylphenyl) ethyl)-4H-1,2,4- triazole-3-thiole. It is then refluxed with different aldehydes in the presence of ethanol and HCl to produce the title compounds. The synthesized compounds are recrystallized from ethanol and are analyzed for their physical and spectral data. They are screened for their anti-microbial activity and it was found that the title compounds are found to have moderate to good antimicrobial activity.
