4-Toluenesulfonyl chloride → (3-(3-iodo-1-tosyl-1H-pyrrolo[2,3-b]pyridin-5-yl)phenyl)(morpholino)methanone

Participants

Reaction Steps

A mixture of (3-(3-iodo-1H-pyrrolo[2,3-b]pyridin-5-yl)phenyl)(morpholino)methanone (600 mg, 1.38 mmol). p-toluenesulfonyl chloride (528 mg, 2.77 mmol), potassium hydroxide (50% w/v in water, 0.387 mL, 3.45 mmol) and tetrabutylammonium hydroxide (40% w/v in water, 0.448 mL, 0.69 mmol) in toluene (5 mL) was stirred at room temperature for 15 hours. Water was added to the mixture and the aqueous mixture was extracted by ethyl acetate (3×). The organic layers were combined, dried over sodium sulfate, filtered and concentrated to dryness. Silica gel chromatography of the crude product afforded (3-[3-iodo-1-tosyl-1H-pyrrolo[2,3-b]pyridin-5-yl]phenyl)(morpholino)methanone (600 mg, 74% yield) as yellow solids. MS: m/z 588.1 (M+H+).
