실험 절차

By replacing the 1-amidino-4-(4-pyridyl)-5-amino-pyrazole employed in Example 1C with an equivalent quantity of 1-amidino-4-(2-pyrazinyl)-5-aminopyrazole and following substantially the same procedure described in Example 1C there is obtained a 75% yield of 4-amino-8-(2-pyrazinyl)-pyrazolo[1,5-a][1,3,5]triazine. The product separates from boiling dimethylformamide in crystals melting above 360° C.
