A 3.0 gm. portion of 6-phenyl-imidazo[1,5-d]-as-triazin-4(3H)-one is stirred with 100 ml. of chloroform. The mixture is heated slightly and a solution of one ml. of bromine in 10 ml. of chloroform is slowly dripped into the reaction mixture. The mixture is fefluxed for 1 hour, cooled to room temperature, and filtered. To the solid is added aqueous Na2CO3 and chloroform and the mixture is shaken in a separatory funnel. The remaining solid and the organic phase are combined and evaporated on a steam bath. Methanol and 2-propanol are added and the mixture is treated twice with charcoal.
