Water → Propane-1-sulfonic acid {3-[(5-bromo-1H-pyrrolo[2,3-b]-pyridin-3-yl)-hydroxy-methyl]-2-fluoro-phenyl}-amide

Participants

Reaction Steps

To 5-bromo-7-azaindole 67 (312 mg, 1.58 mmol) in methanol (28 mL) were added propane-1-sulfonic acid (2-fluoro-3-formyl-phenyl)-amide (503, 370 mg, 1.5 mmol) and potassium hydroxide (422.8 mg, 7.5 mmol) under an atmosphere of nitrogen. The reaction was stirred at room temperature overnight, then poured into water and extracted with ethyl acetate. The organic layer was dried over anhydrous sodium sulfate, and filtered. The filtrate was concentrated and purified by silica gel column chromatography eluting with 20% ethyl acetate in hexane to give the desired compound as white solid (504, 300 mg, 45.0%).
