2-Amino-4-aryl thiazoles and their derivatives have long been used as precursors for the synthesis of biologically active molecules. Therefore new antifungal compounds IV(a-e) have been synthesized incorporating 2-Amino-4-aryl thiazole. The title compounds were synthesized through isolable intermediates. All the synthesized compounds have been characterized by their elemental analysis, 1HNMR and Mass spectra. The synthesized compounds were evaluated in vitro for their antifungal activity against the test fungi by poisoned food technique; at 1000, 100 and 10 ppm using Czapek's agar medium. A standard commercial fungicide Dithane M-45 was also tested under similar conditions for comparison. It was found that all the compounds were antifungal active but amongst them IVd displayed fungicidal action comparable with that of commercial fungicide Dithane M-45.
