実験手順
5.0 g. of 7-amino-5-diallylamino-2H-[1,2,4]oxadiazolo[2,3-a]-s-triazin-2-one are suspended in 7 ml. of triethylamine and 150 ml. of methylene chloride. 3.4 ml. of 4-chlorobenzoyl chloride in 35 ml. of methylene chloride are added dropwise while stirring and cooling to about 0° C. The mixture is subsequently stirred at about 0° C. for 1 hour. Water is then added thereto and the pH is adjusted to 4 with dilute hydrochloric acid solution. The two phases are separated and the aqueous phase is extracted twice with methylene chloride. The combined organic extracts are dried over sodium sulfate and evaporated to dryness under reduced pressure. The residue is recrystallized from methylene chloride and diethyl ether, there being obtained pure p-chloro-N-{5-diallylamino-2-oxo-2H-[1,2,4]oxadiazolo[2,3-a]-s-triazin-7-yl}benzamide having a melting point of 192°-194° C.
