Reaction Steps

6 g. of diethyl 6-diallylamino-s-triazine-2,4-dicarbamate-3-oxide are suspended in 120 ml. of dimethylformamide and warmed to 140° C. for 20 minutes under an argon atmosphere and while stirring. The solvent is then evaporated off under reduced pressure and the residue is recrystallized from methylene chloride/ethanol/diethyl ether, there being obtained pure ethyl 5-diallylamino-2-oxo-2H-[1,2,4]oxadiazolo[2,3-a]-s-triazine-7-carbamate, having a melting point of 172°-174° C.
