The quantitative nucleophilic reactivity of alkyl and dialkylimidazo [1,2-a] pyridines towards methyl iodide is described. In the series of monomethyl derivatives the 7-methyl compound is the most activated and the 8-methyl compound the most deactivated. The effects of two alkyl substituants on the rate of alkylation are additive in the absence of intramolecular steric interaction. On the contrary a
