A series of N-[4-(coumarin-3-yl)thiazol-2-yl] aromatic aldehyde hydrazones have been prepared via the condensation of thiosemicarbazone with α-bromoacetyl coumarin, using microwave heating methodology. The yield was ranged from 69% to 97%. Their chemical structures have been confirmed by means of IR, 1H NMR and HRMS. Bioassay of the title compounds indicated that some of them exhibited good antibacterial activity.
