1,2-Hydrazinedicarboxamide → 4-[[3-[(3,5-Dioxo-1,2,4-triazolidin-4-yl)methyl]phenyl]methyl]-1,2,4-triazolidine-3,5-dione

반응 단계

64.2 g of hydrazodicarbonamide and 37 g of m-xylylene diamine in 300 ml of N-methyl pyrrolidone are heated with stirring for 4 hours to 175° C. and for 30 hours to 200° C. The solvent is then distilled off in vacuo and the residue is recrystallised from chloroform, giving 58 g (70% of the theoretical) of 1,3-bis-(1,2,4-triazolidine-3,5-dione-4-yl-methyl)-benzene in the form of colourless crystals melting at 244° to 246° C.
