Reaction Conditions

Reaction Steps

184.5 g (1.0 mol) of cyanuric chloride was dissolved in 800 mL of acetonitrile at room temperature, and 303.7 g (5.0 mol) of 28%-aqueous ammonia was added dropwise into the solution cooled to 0° C., over 2 hours while vigorously stirring and maintaining the reaction temperature at not more then 10° C. After the completion of dropwise addition, cooling was stopped, and stirring was continued for 1 hour at room temperature, followed by gradually heating to 45° C. and allowing to further react for 4 hours. After cooling, a product was filtered, followed by washing with a large quantity of water. The filtered product was dried at 50° C. in vacuo for 6 hours to obtain 115 g (a yield of 79%) of the above-identified compound.
