Procedure

2 g of 2-[3,5-dichloro-4-(4-methylsulfonylphenoxy)phenyl]hexahydro-1,2,4-triazine-3,5-dione were suspended in 10 ml of acetic anhydride. 1 ml of concentrated sulfuric acid was added dropwise, during which there was a slight increase in the temperature of the suspension and the starting material slowly dissolved. The mixture was then stirred at room temperature for 2 to 3 hours, and was subsequently stirred with water. The product was filtered off with suction, washed with water and dried, and recrystallized from a little glacial acetic acid, melting point 267° C.
