실험 절차

To 5-(1-benzenesulfonyl-5-bromo-1H-pyrrolo[2,3-b]pyridin-3-ylmethyl)-6-fluoro-pyridin-2-ylamine (167, 0.342 g, 0.741 mmol) in 10 mL of acetonitrile, 5-fluoro-2-methoxy-pyridine-3-carbaldehyde (37, 0.118 g, 0.763 mmol), triethylsilane (0.529 mL, 3.71 mmol) and trifluoroacetic acid (0.286 mL, 3.71 mmol) were added. The reaction was heated at 80° C. for 4 hours, then concentrated under vacuum and combined with aqueous potassium carbonate and extracted with ethyl acetate. The organic layer was washed with water and brine, then dried over magnesium sulfate, filtered and the filtrate concentrated under vacuum. The resulting material was purified by silica gel column chromatography eluting with ethyl acetate and hexane. Appropriate fractions were combined and concentrated under vacuum to provide the desired compound as an off-white solid (168, 367 mg). MS (ESI) [M−H+]−=599.6 and 601.6.
