Abstract:
A group of ethyl 6-methylimidazo[2,1-b]thiazole-5-carboxylates and 2-methylimidazo[2,1-b]benzothiazole-3-carboxylates was prepared by reaction of ethyl 2-chloroacetoacetate with some 2-aminothiazoles and 2-aminobenzothiazoles, respectively. Such reactions may sometimes afford a side product which was isolated and characterized. The ethyl esters were then converted into the corresponding acids by hydrolysis. Three of these acids were evaluated for antiinflammatory, analgesic, and antipyretic activities, as well as for ulcerogenic potential.
