Dimethylformamide → 5-{3-[2,6-difluoro-3-(propane-1-sulfonylamino)-benzoyl]-1H-pyrrolo[2,3-b]pyridin-5-yl}-pyridine-2-carboxylic acid ethylamide

Participants

Reaction Steps

To 5-(3-{[2,6-difluoro-3-(propane-1-sulfonylamino)-phenyl]-hydroxy-methyl}-1H-pyrrolo[2,3-b]pyridin-5-yl)-pyridine-2-carboxylic acid ethylamide (73, 50 mg, 0.094 mmol) dissolved in 0.76 mL of tetrahydrofuran, Dess-Martin periodinane (48 mg, 0.113 mmol) was added, followed by 1 mL of dimethylformamide. The reaction was allowed to stir at room temperature for 1 hour, then quenched with water and the aqueous layer extracted with ethyl acetate. The organic layer was washed with brine, dried over sodium sulfate, filtered and the filtrate concentrated under vacuum. The resulting residue was purified by silica gel column chromatography to provide the desired compound (P-2151, 30.6 mg). MS (ESI) [M+H+]+=528.2.
