8-Amino-2,3,6-trimethylimidazo[1,2-a]pyridine (0.38 g, 2.16 mmol) and 2-ethyl-4-fluoro-6-methylbenzylbromide (0.50 g, 2.16 mmol) were dissolved in 10 ml dimethoxyethane. Potassium iodide (0.2 g, 1.2 mmol) and Na2CO3 (0.4 g, 3.8 mmol) were added and the mixture was refluxed for 6 hours. The solvent was evaporated and the residue was purified by column chromatography on silica gel using a mixture of methylene chloride and ethyl acetate (60:40) as eluent. 203 mg (29%) of the title compound was obtained.
