Abstract
Synthesis of the novel potassium salts of 5-dinitromethyl-7-alkylamino-1,2,4-triazolo[4,3-a]-1,3,5-triazines 9a-c was performed by heating (in DMSO) 2-alkylamino-4-ethoxymethylidenehydrazino-6-dinitromethyl-1,3,5-triazines 8a-c, obtained by treating of the corresponding 2-alkylamino-4-hydrazino-6-dinitromethyl-1,3,5-triazines 5a-c with orthoformic ester. 2-Alkylamino-4-hydrazino-6-dinitromethyl-1,3,5-triazines were obtained by a sequential substitution of the methoxy groups of the potassium salt of 2,4-dimethoxy-6-dinitromethyl-1,3,5-triazine with an alkylamine (dimethylamine, morpholine, pyrrolidine) and hydrazine.
