Versuchsvorschrift
A reaction mixture of 0.98 g of 3-amino-5-methyl-1,2,4-triazole and 1.76 g of 3-dimethylamino-1-(3-pyridyl)-2-propene-1-one in 25 ml of glacial acetic acid was refluxed for six hours. The procedure was continued as for Example 1 to give 0.85 g of the product of the Example as colorless crystals, mp 244°-245° C.
