Participants

Reaction Steps

To a stirred solution of 5.25 g (00246 mole) of acetaldehyde 4-chloro-3-nitrophenylhydrazone in 25 ml of acetic acid was added dropwise a solution of 2.0 g (0.0246 mole) of potassium cyanate in 5 ml of water. After complete addition, 50 ml of an aqueous 5% sodium hypochlorite solution was added dropwise, forming a precipitate. After about 1/2 hour, the solid was collected by filtration and dried to yield 5.4 g of 1-(4-chloro-3-nitrophenyl)-4,5-dihydro-3-methyl-1,2,4-triazol-5(1H)-one.
