Abstract
The reaction of 2,4-diazido-s-triazines 1 with an equimolar amount or a two-fold molar excess of ethyl cyanoacetate in the presence of triethylamine in DMF affords the corresponding mono- 2 or diamino derivatives of s-triazine 3; on heating 2,4-diazido-s-triazines 1a–d with a two-fold molar excess of acetoacetone or ethyl acetoacetate in the presence of triethylamine in ethanol the corresponding 1,2,3-triazolo-s-triazines 4a–f are formed.
