Novel 2-(5-R-1,3,4-thiadiazol-2-yl)aminothiazolin-4-ones 6a-h and 2-imino-3-(5-R-1,3,4-thiadiazol-2-yl)thiazolidin-4-ones 7a-h were prepared by treating N-(5-R-1,3,4-thiadiazol-2-yl)thioureas 4a-h with chloroacetic acid on various solid supports under microwave irradiation. Tautomeric mixtures of compounds 6a-h and 7a-h were obtained in all cases. In alkaline and neutral media, compounds 6a-h were the major products, while ill acid media, 7a-h were the major products.
