Participants

Reaction Steps

To a solution of 2,7-dimethyl-1H-imidazo[4,5-b]pyridine (4.29 g) in chloroform (43 ml) was added m-chloroperbenzoic acid (80%, 7.55 g) at room temperature, and the mixture was refluxed under heating for 1 hr. After cooling to room temperature, the reaction mixture was directly purified by silica gel column chromatography (chloroform/methanol=9/1) and pulverized in ethyl acetate to give the objective compound (4.61 g) as a brown powder.
