Reaction Conditions

Reaction Steps

A mixture of 2-(4-chlorophenyl)-3H-imidazo[4,5-b]pyridine-3-acetamide (1.84 g, 0.0064 mole), glacial acetic acid, and m-chloroperbenzoic acid (4.4 g, 0.0256 mole) was heated at 60° C. for a total of 4 hrs. The reaction mixture was diluted with water and the organic acid which precipitated was filtered. The aqueous filtrate was neutralized for peroxides with 10% sodium sulfite. The aqueous solution was evaporated to dryness and the residue was treated with methylene chloride/saturated sodium bicarbonate. The insoluble precipitate was filtered, washed with methylene chloride and water, and dried at 50° C. under high vacuum overnight to give 1.0 g (52%) of title compound, mp. 272°-75° C. with decomposition.
