실험 절차

Into a reaction flask under nitrogen, 5-bromo-1H-pyrrolo[2,3-b]pyridine (4, 1.00 g, 5.08 mmol) is combined with (2,4-difluoro-3-formyl-phenyl)-carbamic acid methyl ester (3, 1.09 g, 5.08 mmol), 10 mL of methanol and potassium hydroxide (0.41 g, 7.31 mmol). The reaction is stirred at room temperature overnight, then diluted with 30 mL of water and extracted with 1×50 mL, then 2×30 mL of ethyl acetate. The organic layers are combined, dried over magnesium sulfate, filtered and the filtrate concentrated under vacuum. The resulting material is purified by silica gel column chromatography, eluting with a gradient of ethyl acetate:hexane. Appropriate fractions are combined and concentrated under vacuum to provide the desired compound (5, 1.91 g, 91%).
