Participants

Reaction Steps

A 20 g portion of 2,4-dichlorophenylhydrazine hydrochloride was added to 200 ml of water and the solution was heated to 80°. Then 6.8 g of potassium cyanate was dissolved in 75 ml of water, and that solution was added dropwise to the first solution. The mixture was stirred for 4 hours at 80°, and it was then cooled. The product was collected by filtration, dried, and recrystallized from ethanol to obtain 11.8 g of the desired intermediate.
