containing thiazole unit was achieved with condensation of thiosemicarbazones and ω‐bromoacetophenone at room temperature. This mild, convenient, and efficient method affords the desired products with good to excellent yields. Their structures have been determined by X‐ray diffractional analysis, 1H‐NMR, MS, elemental analysis, and IR. Thiosemicarbazones were prepared by the condensation of thiosemicarbazide
