실험 절차

1 g of 2-[3,5-dichloro-4-(4-methylsulfonylphenoxy)phenyl]hexahydro-1,2,4-triazine-3,5-dione was suspended in 10 ml of formic acid. 5 ml of propionyl chloride and 1 ml of concentrated sulfuric acid were successively added dropwise, and the mixture was stirred at 80° C. for 5 hours. After it had been cooled, a further 10 ml of propionyl chloride were added to complete the reaction, and the mixture was again heated at 80° C. for 5 hours with stirring. It was then poured onto ice-water, and the precipitate was filtered off with suction and extracted by boiling with a little toluene. The residue was recrystallized from isopropanol/diisopropyl ether, melting point 212° C., decomposition.
