Reaction of 3-nitro- and 3-ethoxycarbonyl-1,2,4-triazolo[5,1-c]-1,2,4-triazin-4-ones with 1-adamantanol (or 1-adamantyl nitrate) in concentrated sulfuric acid or with 1-bromoadamantane in sulfolane affords N-adamantyl derivatives. The adamantylation of 3-nitro-1,4-dihydro-7H-1,2,4-triazolo[5,1-c]-1,2,4-triazin-4-one yields a mixture of N-8- and N-1-isomers that undergo interconversion in concentrated sulfuric acid along intermolecular mechanism.

摘要:
A general method for inclusion of the, N-15 label into the position 1 of 6-nitro-1,2,4-triazolo[5,1-c][1,2,4]triazin-7-one by using (KNO3)-N-15 has been developed.
