Reaction Steps

NaBH4 (0.084 g, 2.21 mmol) was added to a solution of 5-nitro-1-(phenylsulfonyl)-1H-pyrrolo[2,3-b]pyridine-2-carbaldehyde (611 mg, 1.844 mmol) in THF (18.3 mL) and methanol (1.8 mL) at 0° C. The reaction mixture was stirred for 1 hour. It was then treated with water and ethyl acetate, and the layers were separated. The aqueous layer was extracted with ethyl acetate. The combined organic layers were dried with sodium sulfate, filtered and concentrated in vacuo. The crude product was purified by flash chromatography to afford (5-nitro-1-(phenylsulfonyl)-1H-pyrrolo[2,3-b]pyridin-2-yl)methanol (0.26 g, 42% yield).
