| Abstract: | ![]()
An array of novel piperazino pyrimidinyl acetamides, a class of hybrid bis heterocycles are synthesized in “one‐pot” by microwave irradiation method catalyzed by heterogeneous NaHSO4.SiO2 catalyst in dry media and are characterized by melting point, elemental analysis, MS, FT‐IR, one‐dimensional NMR (1H and 13C) and two‐dimensional 1H‐1H COSY and 1H‐13C HSQC spectral data. |
