Hypoxanthine 7-oxide (IV) has been synthesized for the first time from 6-chloro-5-nitro-4(3H)-pyrimidinone (I) through the intemediates II and V; catalytic hydrogenolysis, methylation followed by catalytic hydrogenolysis, and isomerization under acidic conditions of IV supported the correctness of the assigned structure.
