Abstract
Several new aminopyrazolo[1,5—a]pyrimidines were synthesised by condensation of 3,5‐diamino‐4‐(ethoxycarbonyl)pyrazole (1) with β‐bifunctional reagents. The azo analogues of pyrazolo[1,5—a]pyrimidines, i. e. pyrazolo[1,4‐c]‐as‐triazines, were synthesised by coupling of diazotized 1 with agents containing active hydrogen.
