Studies on Pyrazolo [3, 4-d] pyrimidine Derivatives. IV. On 1-Methyl-and 1-Phenyl-1H-pyrazolo [3, 4-d] pyrimidine 5-Oxide

Various reactions usually carried out on heterocyclic N-oxides were examined on 1-methyl-(IIm-0) and 1-phenyl-1H-pyrazolo [3, 4-d] pyrimidine 5-oxide (IIp-0) prepared from the condensation-cyclization of 1-methyl-(IIIm-1) or 1-phenyl-5-amino-4-hydroxyiminomethyl-1H-pyrazole (IIIp-1) and ethyl orthof...
