Abstract
Pyrazolo pyrimido pyrimidine (4a–k) was prepared by the reaction of compound 3‐cyano‐4‐imino‐2‐(methylthio)4H‐pyrido[1,2‐a]pyrimidine (3) with hydrazine hydrate, phenyl hydrazine, 2‐hydrazino benzothiazole, and 6‐substituted hydrazine benzothiazole in N,N‐dimethylformamide and anhydrous potassium carbonate. These synthesized compounds were characterized by elemental analysis IR, 1H NMR, and mass spectral data.
