An efficient novel one‐pot synthesis of pyrazolyl‐thiadiazinyl‐2 H ‐chromen‐2‐ones. In this process, an equimolar mixture of substituted 3‐(2‐bromoacetyl)‐2 H ‐chromen‐2‐ones, thiocarbohydrazide and pentane‐2,4‐dione were taken in absolute ethanol. All these synthesized compounds were characterized by their analytical and spectral data.
