Water → 2,2'-(Piperazine-1,4-diyl)bis(4,6-dichloro-1,3,5-triazine)

Participants

Reaction Steps

Piperazine (8.0 g, 92.9 mmol) is added over a 20 minute period to a mixture of 34.3 g (186 mmol) of cyanuric chloride, 19.7 g of sodium carbonate, 80 ml of water and 200 ml of toluene maintained at a temperature of 5°-10° C. The reaction mixture is stirred for 3 hours at ambient temperature. The precipitate is filtered and washed with water and toluene to obtain 26.0 g (73% yield) of N,N'-bis-(2,4-dichloro-1,3,5-triazin-6-yl)piperazine.
