실험 절차
In 20 ml of acetic acid was dissolved 2.0 g of 2-[4-(4-chloro-α-cyanobenzyl)-3,5-dichlorophenyl]-4,5-dihydro-1,2,4-triazin-3(2H)-one. To the solution was added three times as much mol. of 30% hydrogen peroxide. The reaction was allowed to proceed for 3 hours at 100° C. After completion of the reaction, the reaction mixture was poured into ice-water. Resulting crystalline precipitate was collected by filtration to afford 1.8 g of the titled compound as colorless crystals, m.p. 290-292° C.
