On irradiation with a high-pressure mercury lamp, 9-phenyl-8-azapurine in dioxane gave 9i/-pyrimido[4,5-i>]indole in 33% yiel whereas 54% was obtained in methanol. Nine derivatives of this azapurine, carrying various substituents in the 6 position, behaved similarly (32-91% yields). The principal by-products arose from (1) replacement of hydrogen in the 4 position of the pyrimidoindole by dioxane or methanol residues, (2) reaction with benzene, when used as a solvent, to yield 4-anilino-5-phenylpyrimidine, and (3) reaction with dioxane to furnish 4-anilinopyrimidines. l,3,7-Trimethyl-8-azapurine-2,4-dione, irradiated with diethylamine in acetonitrile, gave 6-diethylamino-1,2-dimethyl-5-methylaminopyrimidine-2,4-dione (66% yield). However, photolysis in methanol gave 5-hydroxy-l,3-dimethyl-6-methoxypyrimidine-2,4- one (22% yield).
