NITROAZINES. 15. CONTRACTION OF THE PYRIMIDINE RING IN 6-NITROAZOLOPYRIMIDINES

It is shown that contraction of the pyrimidine ring occurs when 6-nitro-7-oxo-4,7-dihydroazolopyrimidines are heated with hydrazine hydrate.Complexes of 4-nitropyrazole with 5-aminoazoles, the structures of which were proved by x-ray diffraction analysis, are formed in a similar reaction of nitrosubstituted azolopyrimidines that do not contain an oxo function.
