Abstract: 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.

Keywords: LLM-105, 2,6-dialkoxy-3 ,5-dinitropyrazine, 2,6-dialkoxypyrazine,
nitration, amination.
