m-Chloroperbenzoic acid → HCID 178526231, compound

Participants

Reaction Steps

m-Chloroperbenzoic acid (25 wt % water content, 322 mg, 1.40 mmol) in ethyl acetate (5 mL) was gradually added dropwise to 5-bromo-1H-pyrrolo[2,3-b]pyridine (184 mg, 0.934 mmol) in ethyl acetate (10 mL), and the reaction mixture was stirred at room temperature for 6 hours. After addition of saturated aqueous sodium hydrogen carbonate, the reaction mixture was extracted with chloroform, and the organic layer was dried over anhydrous sodium sulfate and concentrated under reduced pressure. The residue was mixed with a mixture of ethyl acetate/hexane=1/1 (v/v), and the solid was collected by filtration, washed with hexane and dried under reduced pressure to give the title compound as a light brown solid (150 mg, yield 75%).
