| Product | HCID 21495091 | HCID 21495091 | 80% |
Reaction Steps
By replacing the 1-amidino-4-(4-pyridyl)-5-aminopyrazole in Example 1C with an equivalent quantity of 1-amidino-4-(4-pyrimidinyl)-5-aminopyrazole there is obtained an 80% yield of 4-amino-8-(4-pyrimidinyl)-pyrazolo-[1,5-a][1,3,5]triazine which separates from boiling dimethylformamide in crystals melting at about 340° C. (dec.).
