Procedure

200 mg of 7-methyl-2-methylthio-3H-imidazo[4,5-b]pyridine and 370 mg of methyl 2-(4-bromomethylphenyl)benzoate was dissolved in dimethylformamide, and 48 mg of sodium hydride was added at room temperature to the solution under stirring. The reaction was allowed to proceed for 30 min. Water was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The extract was dried over magnesium sulfate, and the solvent was distilled off in vacuo. The residue was purified by silica gel chromatography (benzene:ethyl acetate=10:1→3:2) to prepare the intended product as a colorless oleaginous substance. The yield was 60 mg.
