Procedure
To a solution of 4.5 gm. of 8-methyl-6-phenylimidazo-[1,5-d]-as-triazin-4(3H)-one in 100 ml. of pyridine is added 5 gm. of phosphorus pentasulfide. The reaction mixture is heated at 100° C. for 8 hours, filtered, and poured into dilute hydrochloric acid. The precipitated product is isolated by filtration, washed with water, and dried.
