Hydrogen Peroxide → 2-(3,5-Dichloro-4-(4-chlorobenzyl)phenyl)-1,2,4-triazine-3,5(2H,4H)-dione

Participants

Reaction Steps

In 2 ml of acetic acid were dissolved 0.2 g of 2-[3,5-dichloro-4-(4-chlorobenzyl)phenyl]-4,5-dihydro-1,2,4-triazine-3(2H)-one and 0.2 ml of hydrogenperoxide (30%). The reaction was allowed to proceed for 3 hours at temperatures ranging from 100 to 110° C. To the reaction mixture was added 20 ml of water to cause precipitation of the titled compound as crystalline product. The product was collected by filtration. The yield was 85%. m.p. 175-176° C.
