Procedure

A stirred suspension of cyanuric chloride (3.7 g, 30 mM) in water (25 mL) was treated with NH4OH (2.42 mL of a 28% solution diluted to 7.5 mL) at 0° C. Stirring was continued for 1 hr at 0° C. and 0.5 hr at 10° C. The product was filtered and rinsed with water until the filtrates were neutral. Drying (60° C., 0.2 mm) provided 2.84 g, (86%), mp=234°-235° C.
