Research on heterocyclic compounds. XIX--2-Methylimidazo[1,2-a]pyridine-3-acetic acids.

A group of methyl substituted imidazo[1,2-a]pyridine-3-acetic acids was synthesized by reaction of some methyl derivatives of 2-aminopyridine with ethyl 3-bromolevulinate and subsequent hydrolysis. These new acidic compounds were tested for their antiinflammatory, analgesic, antipyretic and ulcerogenic activities in order to compare the results with those previously obtained with similar compounds.
