Reaction Conditions

Reaction Steps

To a solution of 1-benzyl-4-methoxy-2-methyl-1H-pyrrolo[3,2-c]pyridine (2) (0.887 g, 3.51 mmole) in anhydrous THF (10 mL) dimethyl sulfoxide (25 mL) was added slowly (via a syringe) and the mixture was cooled to 0° C. Potassium tert-butoxide (1M in THF, 25 mL, 25 mmole) was added slowly. Oxygen was bubbled through the mixture for 45 minutes. The reaction was quenched with saturated ammonium chloride solution, the mixture was extracted with ethyl acetate (3×50 mL). The organic layer was separated, dried over magnesium sulphate and concentrated. The residue was purified by column chromatography (3:1 Hex:EtOAc) to afford intermediate (3). Yield: 1.06 g >100%
