HCID 10490701, compound → 4-[N-acetyl-N-(4-aminophenyl)amino]-4H-1,2,4-triazole

Participants

Reaction Steps

A proper amount of 10% palladium-carbon was added to 15 ml of a methanol solution containing 0.38 g of 4-[N-acetyl-N-(4-nitrophenyl)amino]-4H-1,2,4-triazole and the mixture was subjected to catalytic reduction in the presence of hydrogen gas at room temperature for about 40 minutes. After completion of reaction, the catalyst was removed by filtration, and the resulting filtrate was concentrated under reduced pressure. The residue was purified by silica gel column chromatography to give 0.33 g of 4-[N-acetyl-N-(4-aminophenyl)amino]-4H-1,2,4-triazole from the chloroform/methanol (50/1) eluate.
