Treatment of 5-nitro-1,3,6-trinitrouracil with aryl aldehydes in the presence of piperidine causes the condensation to the 5-nitro-6-styryluracil derivatives, followed by the intramolecular cyclization including piperidine-catalyzed oxidation-reduction to give rise to the corresponding 1,3-dimethyl-7-hydroxypyrrolo[3,2-d]pyrimidine-2,4(1H,3H)-dione (9-hydroxy-9-deazatheophylline) derivatives in a single step. Some properties of these compounds are discussed.
