A series of 2,6-dialkoxy-3,5-dinitropyrazines (R = Me, Et, Pr) has been synthesized and subjected to amination. The yield and purity of the generated 2,6-diamino-3 ,5-dinitropyrazine was found to be independent of the alkoxy group present in the precursor. This contrasts with the behaviour of 1,3,5-trialkoxy-2,4,6-trinitrobenzene (R = Me, Et, Pr), where the purity of the 1,3,5-triamino- 2,4,6-trinitrobenzene (TATB) produced by amination was very dependent upon the alkoxy group.
