Claims20
A compound having the chemical formula:
- wherein R1 is —NH2, and R2 and R3 are independently electron donating groups.
1,2,4-triazolo[4,3-a][1,3,5]triazine-3,5,7-triamine.
A process for the preparation of 1,2,4-triazolo[4,3-a][1,3,5]triazine-3,5,7-substituted, acid salt, comprising the steps of:
- dissolving a 2,4-substituted-6-hydrazino-s-triazine with an acid;
- and,
- mixing the dissolved 2,4-substituted-6-hydrazino-s-triazine with a reagent of the formula RCN, wherein R comprises a leaving group, wherein the 2,4-substituted component of the 2,4-substituted-6-hydrazino-s-triazine independently comprise electron donating groups.
A process for the preparation of 1,2,4-triazolo[4,3-a][1,3,5]triazine-3,5,7-substituted compound, comprising the steps of:
- dissolving a 2,4-substituted-6-hydrazino-s-triazine with an acid;
- mixing the dissolved 2,4-substituted-6-hydrazino-s-triazine with a reagent of the formula RCN, wherein R comprises a leaving group;
- removing acid salt crystals;
- and,
- neutralizing the acid salt crystals by mixing with a substance more basic than 1,2,4-triazolo[4,3-a][1,3,5]triazine-3,5,7-substituted compound, wherein the 2,4-substituted component of the 2,4-substituted-6-hydrazino-s-triazine independently comprise electron donating groups.
